This is episode 42, and we’re diving into a particular category of aviation accidents — those that happen right at the beginning of a pilot’s journey. We’re talking about ab initio training mishaps. Ab initio, Latin for “from the beginning,” refers to a training path designed for aspiring pilots who start with zero flight time. Nothing. Not a minute logged, not a system diagram understood. These courses take students from ground zero to the right-hand seat of a commercial flight deck — through a tightly structured mix of theory, simulator time, and real-world flying. They’re intense and sometimes quite fast. And they aim to do two things: produce skilled, airline-ready pilots and identify those who should probably find another career. Many of these programmes are tied directly to airlines, which means you’re taught from the outset to fly their way — their SOPs, their ethos, their cockpit culture. That brings clear advantages. The pathway is laid out: from the classroom to the cockpit, without the detours of fragmented, school-hopping training. For many, there’s financial backing too — covering tuition, even living costs — opening doors for those who’d otherwise never afford to fly. There’s also the camaraderie. Like a military intake, you form close bonds under pressure, guided by seasoned instructors and surrounded by peers. And at the end, a job may be waiting — conditional on success. But it’s not all lift and no drag. Freedom? Limited. You’re often bonded to the airline for years — and leaving early can come with steep penalties. Career flexibility? Not much. Your training is airline-specific, and if you decide to fly charter or head bush, you may be back at square one. Contrary to the doomsaying of many veteran aviators, the accident rate during ab initio flight training in the United States has fallen by close to 50% — measured per flight hour - it shows between 2000 and 2019, the number of fatal training accidents almost halved. The Aircraft Owners and Pilots Association’s Air Safety Institute has the data to back it up. In the early 2000s, the accident rate hovered around 0.49 per 100,000 flying hours. By 2009, that fell to 0.39. By 2019, the rate dipped to 0.26 per 100,000 hours — a substantial decline. The top three causes of fatal training accidents haven’t changed much over time. They are, in order: 1. Loss of control in flight 2. Midair collisions 3. Controlled Flight Into Terrain — CFIT — the old nemesis flight into the granite cloud.

This is episode 36 and its icy cold out there - it’s time to check out the incidents involving icing - starting with a short list and general description of the causes, then focusing on the two Aeroflot Atonovs accidents in 1971 and a design fault in the ATR-72. There’s an unfortunately long list of commercial airliners lost due to icing, more than 540 accidents and events caused by aircraft icing by the late 1980s in the United States alone and most of these were fatal. Anti-icing and de-icing research can be traced back to the early 1930s and in 1948, two scientists, AG Preston and Calvin Blackman conducted the first successful iced flight experiment in which the drag coefficient increased by 81% when the wing was covered and the pilot reported the plane was almost beyond control. I’m not sure of what aircraft they used but the results were extraordinary. Other research by NASA on the DHC-6 Twin Otter aircraft measured various conditions and ice shapes and their effect on aircraft thrust, landing flaps, and angle of attack. It’s thought that the first recorded case of a commercial airplane accident caused by icing occurred on December 15, 1920 when a de Havilland DH.4 mail plane operated by the United States Post Office Department crashed near Belleville, Pennsylvania, in the USA due to ice accumulation on the wings and control surfaces.There was a happier end to another on 19th December 1946 where a Railway Air Service Douglas Dakota 3 stalled on take-off 1 km north-east of Northolt Airport in London. This was the case of the scheduled service to Glasgow Airport from London. Four crew and one passenger were on board .. Yes, you heard correctly, one passenger.So to matters more terminal if you excuse the extremely cheesy aviation pun. That be the highly unusual twin crashes of the Antonovs in 1971 both caused by ice accretion. ot Antonov An-12s crashed on approach to Surgut International Airport, just nine days apart. The crashes occurred under near-identical circumstances due to the aircraft type’s lack of preparedness for flying in severe icing conditions. It’s the formation of an ice ridge by water droplets beyond the ice protection system and one side anti-icing system that is likely to cause rolling and overturn according to research documents. A case in point of the ridge cause was an ATR-72 crash in 1994. At that time, the airplane was at a severe level of icing condition, and the co-effect of the electric heating de-icing system at the wing leading edge and the natural conditions formed an ice ridge on the second half of the wing, resulting in a negative pressure zone on the one side's aileron.

I’m your host and pilot, Desmond Latham. Every week we tackle a different area of aviation and this week it’s the history of hijackings. The first ever hijacking of a commercial plane took place on the 16th July 1948. It involved a Catalina Seaplane owned by Cathay Pacific and operated by subsidiary Macau Air Transport Company registered in Hong Kong. At that time Hong Kong was still a British Territory. And ironically the plane that took off from the sea was going to be affected by what was called piracy originally. The struggle between the Nationalists and the Communists was in full flow – the civil war reverberated around the region and law and order had collapsed in many parts of China. The Miss Macao, as the seaplane was called, was on a routine flight from Macau to Hong Kong. In 1948 Macao was a Portuguese territory. But it never made it to the rapidly growing metropolis of Hong Kong. The plane was hijacked a few minutes after take-off by four men, three armed with guns, one of whom demanded that the pilot surrender the controls. Just to add to the crazy scenario – he was from Mexico but was not Mexican. The pilot, an American by the name of Dale Warren Cramer, refused to hand over control to the hijackers and at that moment his co-pilot attacked one of the intruders with a flag-post rod. In the confusion, Cramer was shot dead, and collapsed onto the flight controls. The plane went into an uncontrolled dive and crashed into the sea. Miraculously one person survived by jumping out of the emergency exit as the plane hit the ocean. Unfortunately it was one of the hijackers although in a sense some would say its fortunate that at least someone survived to tell the story. Twenty-five of the twenty-six people aboard died in the crash. Through this series you’re going to hear how often one person survives – and its more often than you think.

This is the series that tracks air disasters through history and how each has led directly to the safety we almost take for granted every time we climb aboard an airliner. Last week it was the story of the first recognized commercial air crash involving a dirigible over Chicago in July 1919 that killed 13 people, three on board and 10 on the ground. That led to new no-fly rules over city central business districts. This week we have jumped forward to the crash of Air France 447 which took place in June 2009. Two hundred and twenty eight crew and passengers were on board. None made it out alive. A crucial piece of equipment malfunctioned leading to incorrect decisions being made by the air crew. The piece of equipment is called the Pitot tube. At the end of this episode I’ll update the Short History of section with more details about the background to the PITOT tube. Pitot tubes are amazingly simple yet vital hardware and you can find these on all aircraft, big or small. It’s linked to pressure-sensitive instruments and used to determine airspeed, altitude, and rate of climb or how fast a plane is climbing or sinking. Modern airliners have more than one, but that didn’t make any difference in the early morning hours of June 1st 2009. Air Airbus A330-203 registration F-GZCP took off from Rio de Janeiro at on May 31st 2009 routing to Paris. Because the duration of the flight was more than 10 hours, there were 3 crew which meant each could take a break. The flight's captain was Marc Dubois, while the co-pilots were Pierre-Cédric Bonin and David Robert.[12] There were 9 cabin crew onboard and 216 passengers. Unfortunately for all on board, the first sign of poor aviating that night a severe chain of thunderstorms appeared in the inter tropical convergence zone, the area north and south of the equator which registers cumulo nimbus based storms that can rise to nearly 50 000 feet which is higher than any airliner flies. No large commercial airliner can fly that high.

This series called Plane Crash Diaries is really about how safe aviation has become. This sounds like a contradiction, but its through the experience of more than a century of commercial aviation that experts have been able to build an extremely safe sector in the 21st Century. Decades of improving safety and regulations as well as operating procedures have led to a form of transport that is now regarded as crucial to the development of the world economy. There are more than 2,000 airlines operating more than 23,000 aircraft at 3,700 airports around the world. These airlines serve a total of more than 3.5 billion passengers a year or about 96,000 passengers a day. The commercial aircraft industry has been growing at 5% per year over the past 30 years and is expected to double over the next decade. This is success in anyone’s book. With all those planes flying about, safety is paramount and has been since the early days of aviation. Consider how many aircraft are flying compared to the number of incidents and you’ll agree that aviation is surely one of the safest methods of getting around in the modern world. But it wasn’t always like that. Each accident that has taken place since the first heavier than aircraft commercial aviation began after the First World War has led to improved standards. So in this series we’ll track these accidents from across the one hundred years since the first was logged. That was on July 21st 1919 when a GoodYear blimp the Wingfoot Express, crashed into the Illinois Trust and Savings Building in Chicago. Thirteen people died – three of the five on board the dirigible and ten others on the ground. The accident led to new regulations eventually about how high aircraft should fly above congested city centres. As a pilot I have to follow these to this day even here in South Africa where Air Law states that no Central Business District may be overflown without consent from the Civil Aviation Authority.
