In 1982, an Air Florida Boeing 737 crashed into the Potomac River, Washington D.C., after takeoff from Washington National Airport in icing conditions. Erroneous engine thrust readings (higher than actual), and the co-pilot’s lack of assertiveness in communicating his concern and comments about aircraft performance during the take-off run were among the factors cited (NTSB/AAR 82- 08).
Experts say that one needs to be ‘aggressively’ safe. All communications (verbal or written) and standard operating procedures (SOPs) should be proactive, predictive and preventive. Some of the accidents mentioned could have been prevented.
As can be seen in the diagram shown, the SHELL boundaries are not smooth but inherently full of serrations, and much effort is needed to interact efficiently and seamlessly. Some experts stress that it is Communication in the form of SOPs that ‘lubricate’ the system for smooth interaction between elements’ while the captain (team leader) sets the tone. In fact, where air safety is concerned, Capt. Tony Kern, a human factors expert, says in his book Redefining Airmanship that to maintain air safety, it is imperative that the team leader knows himself, knows his team, knows his aircraft and equipment, knows his mission and, above all, evaluates the risks involved with the task at hand.There can be problems with the interaction within the team (Liveware and Liveware). Sometimes the Captain (Leader) has to be an expert in conflict resolution! (See Figure 01)
Threats and Hazards
Almost every situation in life is full of ‘threats’. When it involves one personally, it becomes a ‘hazard’. In the aviation context, if there is a flock of birds in the vicinity of an aircraft, they constitute a ‘threat’. However, if that flock of birds starts crossing the flight path of the aircraft, it becomes a ‘hazard’ and avoidance action needs to be taken. Remember the ‘Miracle on the Hudson’? The engines failed because of bird ingestion.
Many airports, too, contain manmade threats and hazards which are usually eliminated only after an accident. In fact, pilots say that blood has to be spilt for changes for the better to occur. At many airports high-rise or security-sensitive buildings are built without planning, and no consideration given to air safety, thus violating the law.
The Ratmalana International Airport is a case in point. On the landing approach from the Attidiya side there is the Parliament and Akuregoda Military Headquarters which are prohibited over flying areas. In the vicinity of the Ratmalana International Airport, there is the Kotelawala Defence Academy and Hospital. At the Galle Road end a solid wall creates a hazard for landing and departing aircraft. Elsewhere, at the Puttalam-Palavi airbase a cement factory is in line with the runway, whilst at China Bay-Trincomalee the silos of a flour mill obstruct landing and take-off paths. These hazards at the latter two airports render them useless as ‘alternate’ (alternative) international airports. If sufficient thought had been given to air safety planning, the loss-making Mattala Rajapaksa International Airport in the Hambantota District would never have been built.
The Swiss Cheese Model
Just as one proverbial swallow doesn’t make a summer, one error alone will not create an incident or an accident. Rather, it will be caused by a chain of unsafe events not picked up by the system. The triviality of one such potentially disastrous cause or lapse is echoed in the words of a poem from the 17th century, later popularised by Benjamin Franklin in his Poor Richard’s Almanac: (See Figure 02)
Reasons for accident occurrences are similar. In fact, the Toyota Corporation asks ‘why’ at least five times when determining the ‘root cause’ of a problem.Aircrew members are regularly taught to recognise unsafe patterns highlighted in past accident investigations, so as to nip them in the bud if and when identified.
Professor James Reason postulated the ‘Swiss Cheese’ model, which states that in any organisation, the layers of safety and security controls in place should be able to block, or cover, one another, to prevent accidents. But unfortunately, there are random holes of all sizes in these layers, like slices of Swiss cheese. Hence, the possibility that with the presence of latent conditions and active failures, these holes will align and allow a potentially dangerous situation or practice to go through without being trapped, thus creating an accident or incident. (See Figure 03)
As illustrated in Reason’s ‘Swiss Cheese’ diagram, latent failures of the system are those that compromise safety, having existed and been taken for granted for short or long periods of time; active failures are immediate, unsafe human acts. In fact, the crew (human element) is the last line of defence before an accident or incident occurs.
To illustrate these points, I shall revisit the 9-foot/3-meter concrete wall that was erected several years ago at the Galle Road end of the runway at Ratmalana International Airport.
This wall could be regarded as a man-made hazard. The runway is 1,833 metres (6,014 feet) in length, not long enough by worldwide standards for a so-called ‘international airport’. By international law, at a pre calculated critical speed (known as the go/no-go speed) pilots are allowed only two seconds in which to make a critical decision whether to stop or continue the take-off. According to calculations by the Boeing Company, a decision to stop any later than two seconds (called ‘dither time’) will result in an aircraft reaching the end of the runway at a speed of 60 knots (69 mph).
On a rainy day, if pilots of a medium-sized aircraft decide to abort the take-off three seconds late, they are unable to stop within the paved runway, with deployment of maximum braking and other stopping devices such as reverse thrust, and the aircraft will ‘overrun’. Because the grass in the overrun area is wet and slippery, the brakes are rendered ineffective. Consequently, in the case of Ratmalana, the aircraft will definitely impact the wall and perhaps catch fire as fuel tanks are usually full during departure.
So, the delay in making a decision to reject the take-off rather than continue would be an ‘active’ failure by the crew. The presence of a solid wall at Ratmalana is the presence of a ‘latent’ condition caused by the Airports Authorities. Although the wall is an ‘accident waiting to happen’, the Sri Lanka Air Force (SLAF), which earns ‘welfare’ money from advertisements on the wall, stubbornly refuses to replace it with a frangible fence, that would break on impact and reduce damage to an over-running aircraft and even vehicular traffic on the Galle Road.
Returning to Reason’s ‘Swiss Cheese’ postulation, air accident investigators usually work backwards from the incident/accident, using the ‘model’ to find the root cause, unsafe acts and any failed defences. The best witnesses are, of course, the crew themselves, although they may not want to voluntarily give information if a punitive attitude is adopted by accident investigators and the authorities. It is a long-held belief that the crew involved are damned if they tell the truth and damned if they don’t. In the recent past in Sri Lanka, the Law and the Police were quick to ‘criminalise’ air accidents. Almost two years ago the accountable manager and chief engineer were arrested and remanded for failure to prevent an accident. That is another story.
The protocol should be for an independent team to do a non-punitive inquiry, and if and only if elements of negligence are highlighted in the final accident report, then the law should take its course under the direction and oversight of the Attorney-General. In short, the authorities in Sri Lanka need to get their act together and conduct themselves in a professional, impartial, fair-minded manner.
Accidents don’t only happen to “other people”, and with threats everywhere we have to learn to mitigate and manage them. While it is human to err, could we eliminate error completely? I think not. But pilots can learn to trap and minimise their ability to make errors by using their team effectively, including pre- and post-flight briefings. A common question that should continue to be asked is: “Could we have (as a team) done things better?”
Will automation of some tasks help? Instructors often repeat the adage, “Fly the aircraft and don’t allow the aircraft to fly you.” Conversely, “The aircraft flies by itself. You assist it to fly”. I believe it is the level of automation that matters, depending on circumstances.Bernard Ziegler, a French pilot and engineer who served in Airbus Industrie as senior vice president for engineering – and was the son of Airbus founder Henri Ziegler – was well known for his evangelical zeal for the application of computerised control systems in Airbus airplanes, commencing with the revolutionary A320 airliner. Bernard Ziegler attempted to design the human out of the flight deck in Airbus’s so-called ‘fly-by-wire’ airplanes, which in their early days were involved in a series of incidents and fatal accidents, due mainly to the mismatch of the man/machine interface. So much so that the A320 was called the ‘Scare-bus’ in jest. Even today many Airbus pilots are heard to ask while flying, in perplexed tones: “What is it doing now?” or “I have never seen this happen before.”
A more recent story is that of the Boeing 737 MAX. When I flew the basic Boeing 737-200 many years ago, our Irish instructor called it the ‘thinking man’s aircraft’, a perfect match between man and machine. Somehow, due to design quirks in the newly designed 737 MAX, an automatic system called MCAS (Manoeuvring Characteristics Augmentation System) was incorporated. If the aircraft got into an unusual and unsafe nose-up attitude, MCAS would be automatically activated and lower the nose to a safer angle.
Unfortunately, during the somewhat rushed introduction of the 737 MAX onto the market, many airline crews were not sufficiently trained in how to override the system – if MCAS was activated due to false indications from, say, a computer or instrument malfunction. Worse still, some airlines’ pilots were not even told that their new airplanes were fitted with such a system, and therefore unaware of what to do if and when MCAS became activated for no apparent reason. This ignorance, through no fault of the pilots, resulted in two disastrous MAX crashes, in Indonesia and Ethiopia, with a total loss of 346 lives.
As the ‘cold hard facts’ later emerged, it became apparent that although the ‘MAX’ was arguably a totally new type of aircraft, it was designated as a Boeing 737-800 to minimise legal crew-training time on the type. This extra training was seen as an undesirable burden for Boeing’s customer airlines, who would have to withdraw captains and first officers from the line for training, thus incurring loss of productivity and revenue for the airlines.
Boeing’s intent was, therefore, for the training (non-productive) period to be as short as possible. But in practice corners were dangerously cut. The US regulator, the Federal Aviation Administration (FAA) – in this case the ‘human element’ – went along with the manufacturer’s sales and training programme, which ultimately resulted in incidents, accidents, and loss of life.
In summary, statistics show that although accidents have decreased to a small percentage in terms of flights and hours flown, the number of certified air operators is also increasing, which causes the number of accidents to increase. Difficult as it is to contemplate, it wouldn’t be wrong to say that the potential exists for more human factor-based accidents to occur in future.

Combining local resources,traditional knowledge and science to build a food-secure Sri Lanka
World Food Day 2026: Innovating today for a better food future
by Dr. Kaushalya Wijayasekara
What will be on the Sri Lankan dinner table ten years from now? Will our children be able to get nutritious food at a price their families can afford? Will farmers be able to grow enough despite changing weather and rising costs? And how much of the food we produce will actually reach the consumer, instead of being lost or wasted along the way?
These questions can’t wait. A farmer faces unpredictable weather. A family faces rising food costs. Fruit goes unsold after a good harvest. Some children do not get enough nutrition. The future of food is tied to the future of Sri Lanka itself.
World Food Day 2026 is a chance to look beyond the immediate problems and ask whether we can build a food system that feeds our people well, gives farmers better opportunities, protects the environment and makes better use of what we already have. The answer can be yes, but we will have to think differently.
We are not starting from zero. Sri Lanka has diverse crops, fisheries, traditional food knowledge, indigenous varieties, research institutions, universities and a young generation able to create new solutions. What we need is to bring these together and act. Producing more will not secure our food future on its own. It will depend on how intelligently we produce, process, preserve, distribute and consume food.
Making more of what we already have
Innovation does not always mean inventing something new. Often it means finding better uses for the resources we have.
Sri Lanka grows traditional rice varieties, kurakkan, green gram, cowpea, jackfruit, breadfruit, cassava, sweet potato, coconut and palmyrah. All of them have great potential for modern, nutritious, value-added foods. Jackfruit and breadfruit can be made into flour and other convenient products. Traditional rice varieties can go into new foods that suit changing consumer needs. Palmyrah, with its strong cultural heritage, can create new income through better processing, packaging, quality assurance and market development.
The aim is to connect our traditional food knowledge with modern consumer needs and technology, while keeping our food heritage.
Stop wasting the food we produce
Reducing food loss and waste should be a major priority. Seasonal fruits such as mango, banana, papaya and pineapple can be lost in large quantities when production exceeds demand or when storage, transport and processing facilities are inadequate. With suitable technology, these fruits can become dried products, pulps, powders, beverages and other shelf-stable foods.
Agricultural and fisheries by-products are resources too. They could be turned into food ingredients, animal feed, bio-based products and other useful materials, which would move us toward a more circular food economy.
Technology alone is not enough. We need stronger local processing facilities, cold storage, efficient transport, collection centres and market information systems, especially close to where food is produced. Cutting food loss raises the value of what our farmers and fishers already produce.
Nutrition and food safety come first
Food security means more than having enough food. People also need food that is safe and nutritious.
Sri Lanka can develop affordable, nutritious foods from local pulses, grains, vegetables, fruits and fish. Children and other vulnerable groups should get particular attention. Schoolchildren in particular deserve a focus: safe, nutritious, locally sourced products for school feeding programs would support child nutrition, local farmers and domestic food industries at the same time.
Food safety must stay at the centre of food innovation. Good hygiene, quality control, laboratory testing, traceability and appropriate food safety systems are what make new products safe as well as attractive and nutritious.
A food system that can cope with climate change
Climate change is already affecting agricultural production, water availability, crop yields and food prices. We need food systems that can handle changing conditions. That means climate-resilient crops, efficient water use, soil and water conservation, better storage and resource-efficient food processing.
Traditional knowledge matters here. Generations of Sri Lankan farmers have developed practices suited to local climates and ecosystems. Combining that experience with modern science can give us solutions that fit local conditions and are sustainable. Technology alone will not build the future of food. Science, experience and local knowledge together can.
Give young people a bigger role
Sri Lanka’s universities have an important part to play in shaping our food future. Young people should be encouraged to identify real problems in the food system and work on practical solutions in areas such as food waste, sustainable packaging, nutrition, food safety, modernising traditional foods and digital technologies.
A good research project should not always end as a research paper. Where appropriate, research should be supported to move on to products, technologies, enterprises and community solutions. That needs stronger partnerships between universities and industry, along with mentoring, research funding, business support and market connections. If young researchers and entrepreneurs can turn their ideas into viable food innovations, both consumers and producers will benefit.
A pathway designed for Sri Lanka
We do not need to copy food-system models from other countries. We can build a pathway that suits our own resources, culture and needs. It would bring together local resources, traditional knowledge, scientific research, appropriate technology and entrepreneurship, with farmers, fishers, universities, research institutions, food industries, entrepreneurs and policymakers working side by side.
The goal goes beyond selling raw materials. We need to create more value, reduce waste, improve nutrition, generate jobs and strengthen rural livelihoods. This matters especially for small and medium-scale food enterprises, which can drive local economic development when they get the right technical, financial and market support.
The choices we make today
The food future will not create itself. It will be shaped by what we grow, what we research, what we process, what we consume and what we choose not to waste.
So, the question for World Food Day 2026 is this: what can we do today so that every Sri Lankan has safe, nutritious, affordable and sustainable food tomorrow?
The answers are already around us, in our farms, fisheries, food businesses, universities, laboratories and communities. We have the resources, the traditional knowledge, the scientific expertise and talented young people. What we need now is to connect them and act.
A better food future begins with the choices we make today.

20th Anniversary of Digampathana blast – the day Sri Lanka Navy cried

The Digampathana suicide truck attack on 16th October 2006 remains the deadliest single strike in Sri Lanka Navy history, leaving scars that time cannot erase.
It was a seemingly ordinary Monday morning on 16 October 2006, but the calm of that day would soon be shattered in a way none of us could have imagined. As the Commandant of the Naval and Maritime Academy and Flag Officer Commanding Naval Fleet at Trincomalee, I was aware that a number of my cadets were travelling that morning, part of a convoy of fifteen buses carrying naval personnel from Trincomalee, Colombo, and other bases, heading toward Dambulla to rendezvous with another group. The convoy also included trucks and escort vehicles, a routine movement planned and coordinated with the army to ensure the roads were clear. The morning started quietly. Some personnel greeted friends, handed over their weapons, or strolled to a nearby tea shop. It all seemed so ordinary—too ordinary for what would come next.

Sri Lanka Navy sunk LTTE Ships carrying arms, ammunition and warlike materials thousand miles away from Sri Lanka in Indian Ocean in September and October 2007.
By late morning, both convoys had reached the small ground at Digampathana, near the Sigiriya junction, and personnel mingled briefly, unaware that a carefully orchestrated act of terror was waiting. Then, suddenly, an empty half-truck veered directly into the convoy. It exploded with a ferocity I can still recall as if it were yesterday. Nuts, bolts, and high explosives tore through the air. Pandemonium erupted instantly. I later learned that 107 of our naval personnel were killed on the spot and another 153 critically injured. The scene was indescribable—bodies scattered, vehicles mangled, personal effects strewn across the ground. I remember later hearing that the head of the suicide bomber was recovered more than 100 meters away from the blast, a grim testament to the sheer force of the explosion.
I was in my office at the Naval and Maritime Academy when my mobile phone rang. A young midshipman from the 21st intake called, his voice trembling: “Sir, there was a huge explosion at the convoy point! Many are dead … my batch mate Wijesundara is among them.” I immediately jumped into my jeep with my escort Chief Petty Officer and driver and rushed to Digampathana, relying on every ounce of my driving skill to reach the scene. The journey, which usually took little more than an hour, felt endless that day, each passing mile weighed down by dread.
When I arrived, I was confronted with a sight that no training can prepare you for. The injured were being rushed to Dambulla Hospital, where doctors and nurses worked tirelessly, improvising in ways that saved lives despite the overwhelming chaos. I went back to the site after visiting the hospital. The remains of our naval personnel were scattered across the ground, and someone had begun collecting weapons and protective gear. I immediately contacted Surgeon Rear Admiral Nico Jayasekara and received his instructions: collect all body parts in separate bags and transport them to the Trincomalee Naval Hospital mortuary. This gruesome work had to be done with care and dignity, and it filled the icebox in my vehicle. Through DNA testing initiated by Rear Admiral Nico, we were able to identify every naval personnel lost that day, bringing some closure to grieving families.
The Navy Commander at the time, Vice Admiral Wasantha Karannagoda, was devastated. I had worked closely with him and knew how deeply he cared for his men. He ensured that the fallen were honoured with full ceremonial naval funerals at Welisara Naval Base, attended by families and comrades. Sixty-seven funerals were conducted in a single day—a number that still haunts me.
The Digampathana attack remains the largest single loss of naval life in our history. It was a day of sorrow, but also a day that reinforced our resolve. The tragedy galvanized the Navy to target the LTTE Sea Tiger wing with renewed determination and reshaped our maritime operations forever. Every time I think of that day, I remember not just the lives lost, but the courage, professionalism, and dedication of those who survived, those who treated the injured, and those who ensured the fallen were honored properly. May the souls of our naval hero’s rest in peace, their sacrifice guiding us and inspiring generations of naval personnel to come.

‘Murder at Whitby Abbey’
Tales of Mystery and Suspense – 24
I was intrigued by the title of a book I found in a book drop at the condominium of a friend, Murder at Whitby Abbey, and I brought it home with me though I will not be able to return it in the near future. It was described on the cover page as ‘a standout in the crowded medieval mystery field’, though I fear I do not know of other books in this field, apart from the Cadfael series, which I have dealt with earlier.
The book, by Cassandra Clark, is set during the reign of Richard II and has as a backdrop his precarious position, which led to his being replaced, and murdered, by his cousin Henry, who reigned as Henry IV. It is a gloomy book, the action taking place in the twelve days of Christmas leading up to the Epiphany. And the gloom is pervasive, even though this is supposed to be a time of festivity, with mummers performing, and many of those in the guest house where the heroine stays going to town to enjoy themselves, with much drinking and much music, which also fills the guesthouse.
The heroine Hildegarde is a nun, sent to try to acquire a relic being sold by Whitby Abbey, though this was also a penance set by the Abbot of the monastery that governed her abbess because she had had sex with a man. Soon after she and her companions reach the Abbey set high on a cliff, she finds that there are other bidders, and soon suspects that the hierarchy, not perhaps the Abbot who seems a weakling, but his rapacious bursar, is determined to make money, and not above creating false relics to sell to several aspirants.
After Hildegarde and her Cistercian companions – Whitby is a Benedictine Foundation – two monks, Gregory and Egbert, and a young priest Mark, reach the abbey, they find that Aelwyn, a monk they had met on their way to the guesthouse had died. This was in the apple store, and they realize, when they find the surplices of novices stuffed into the air vents, that he had been left to suffocate in the overwhelming scent of apples.
The Cistercians are asked to look into the death, perhaps because they are likely to get no cooperation from the Abbey folk, but perhaps because those in charge are keen to know what happened. And the infirmarer, an old monk, suggests Hildegarde talk to a man called Edred who worked for the bursar, and had been a friend of Aelwyn’s. But Edred too is killed, before he can keep an appointment he had made with Hildegarde, drowned in a pool near the farmhouse of the Abbey.
Meanwhile tensions arise between the fisherfolk and the abbey for the bursar wants to charge them for using the beach that technically belongs to the abbey to dry their fish and their nets. This leads to physical battles, when the guards used by the abbey, under the command it seems of the bursar whose determination to make money is not resisted by the abbot and the prior, try to storm the area where the fishermen live.
Hildegard finds out more about what had happened through two youngsters, one of whom Torold is the son of Aelwyn by a woman who worked as a prostitute for a cartel, and with whom Mark fell in love. The other works on the farm and had seen Edred meet someone near the pool, after which that someone left the place by himself. And the boy had also found in the pool a sort of dagger with the seal of the abbey.
He and his dog, and Torold who follows her, rescue Hildegarde from a man at arms who has waylaid her and tries to rape her earlier. Escaping into the abbey she was nearly been raped then by the bursar, but she managed to escape, in the process setting fire to him and the muniments room, which led, when he was rescued, to the discovery of a box with the money he said had been stolen, blame being cast on both Aelwyn and Edred.
Matters come to a head when the fisherfolk try to storm the abbey, being resisted by the men at arms stationed on the towers. But then Hildegarde realizes that behind the murders was the bursar’s clerk, whom she pursued to the cathedral. There is great drama then as she escapes from him when he tries to kill her, and then from the man at arms who had tried to both rape and kill her, but they both fall from the scaffolding she had climbed, the latter coming from a tower where he had been stationed.
Both of them think they run the rapacity of the abbey, the latter claiming to work for the nobles opposed to Richard, who is presented throughout the book as devoted to his subjects, not to power or money. But though the villains die, the bursar continues, having got over the hysteria the fire had caused and his acknowledgment then of guilt – and though the abbot and the prior seem less vicious, whether they will be able to assert themselves is questionable.
Before the climax, when the others in the guesthouse were leaving, Hildegarde found that two of them were in possession of the relic, for which they seem to have paid well. Hildegarde herself had made a derisory offer, but before she leaves the abbot gives her the relic, perhaps in gratitude for what she and her fellow Cistercians had discovered, the abbey having made as much money as it needed and more from the gullible other buyers.
Mark’s inamorata is saved from the stews because she moves in with Edred’s widow whom the bursar had thrown out of the rooms he occupied when her husband was found dead. Hildegarde had paid for lodgings, in a house run by the man who ran the brothels, but he had a kindly side and was going to finance them to make nets for the fishermen.
So, the Cistercians set off for their home as swiftly as they can to get there on the day of the Epiphany, having stopped en route to pray for King Richard whose birthday it was.
