Although the video looks terrifying, the event is far from a disaster. The most likely scenario is the pilot safely flies away as did occur. Even a crash landing is still expected to be survivable. Wings are usually tested to destruction during the certification process. For example the Boeing 777’s wings were bent 24 feet before breaking. The biggest concern is a potential post crash fire as shown in the plane on the cover of my book. In that case all 301 passengers and crew safely evacuated.

The Hamburg incident is very similar to another incident in the Netherlands in 1997. In this case the plane hit with too high a sink rate and collapsed the landing gear. There were no injuries. Airplane wings are actually quite robust. In 1965 an engine fire burned off 25 feet of wing tip. The plane still landed safely.

Illustrating the energy of compressed gas Aloha Flight 243 (April 1988) blew its top in a massive explosive decompression. The effect is identical to the fragmentation of a pin pricked cylindrical balloon. A little bit of scotch tape also illustrates how the fuselage ribbing is designed to prevent a rapid tearing fracture.

Explosive Decompression Blast Hole


18′ by 14′ blast hole. Everyone lived except for one flight attendant standing nearby without seatbelt.

Other Pressure Stories:

I found two examples of people being sucked out of windows. In 1973 an engine fragment knocked out a window. The nearby passenger was slowly sucked out in spite of having his seat belt on. Later it was determined it was slack by 8 inches.

In 1990 a British Airlines pilot was sucked out at 17,300 feet. The left wind screen had been replaced the night before with undersized bolts. He caught his feet in the control column. Flight attendants wrestled his feet out of the control column and held on to him for 20 minutes until they safely landed. The pilot lived to resume his flying career.

Lightening Strikes

Although planes are struck by lightening on average one per plane per year, it is totally safe as shown by this amazing video.

Incredible Evacuation

After a botched landing this Air Bus 330 caught on fire in Toronto in August of 2005. Everyone evacuated safely in spite of 4 of 8 exists being blocked by fire or damage.

People just don’t understand how survivable an airplane crash is. Sure a violent crash can kill everyone. Far more likely is an equipment failure or pilot error during the critical phases of take-off or landing at around 160 mph or less. (Around 400 mph or so the plane will fragment at impact.) Just like the article said: of the 27 DC-10 destroyed in crashes, 85% of the time an average of 90% of the passengers lived.
If I had more space in the New York Times article I would have further said (besides buy the book) the following.

Crashing at lower speeds is survivable. However it is also easy to puncture the sheet metal fuel tanks, ignite fuel and burn the plastic interior. In that case the flight attendants instructions are vital. 300 people do not need 300 different ideas about how to find the nearest exist especially at night with a little bit of smoke, fire and panic.
