Chalk’s Ocean Airways Flight 101 — The Wing That Should Have Been Retired

Chalk’s Ocean Airways Flight 101 lost its right wing during departure from Watson Island, Miami, killing all 20 people on board.

Malaysia Airlines Flight MH17 was shot down by a Buk surface-to-air missile over eastern Ukraine on 17 July 2014, killing all 298 people on board.

El Al Flight 1862 — When the Engine Takes the Wing With It

El Al Cargo Flight 1862 lost the Number 3 and Number 4 engines simultaneously when the inboard midspar fuse pin of the Number 3 pylon fractured due to fatigue cracking at a corrosion pit.

China Airlines Flight 120 — The Fuel Leak Nobody Saw Until It Was Too Late

China Airlines Flight 120 caught fire on the apron at Naha Airport immediately after landing, when fuel that had been leaking from a maintenance-induced puncture in the leading edge fuel tank ignited — most likely on contact with a hot engine or brake component.

TAM Airlines Flight 3054 — The Thrust Reverser, the Wet Runway and No Margin

TAM Airlines Flight 3054 landed at São Paulo Congonhas Airport on a wet runway with one thrust reverser locked out under the MEL, the functioning reverser’s power lever incorrectly positioned at climb rather than idle, and a runway surface whose friction had been degraded by a poorly executed groove-fill repair. The combination was unsurvivable. The

China Airlines Flight 611 — The Repair That Held for Twenty-Two Years

China Airlines Flight 611 broke apart in cruise flight over the Taiwan Strait on 25 May 2002. The aircraft’s aft lower fuselage failed due to a fatigue crack that had grown — undetected — from an improperly repaired tailstrike that had occurred in 1980. Twenty-two years earlier. The repair had been performed out of specification.

Pan Am Flight 103 — Lockerbie and the System That Received a Warning

Pan Am Flight 103 was destroyed by a bomb concealed in a Samsonite suitcase in the forward cargo hold, killing 270 people including 11 residents of Lockerbie.

Air India Flight 182 — The Baggage That Nobody Screened

Air India Flight 182 was destroyed by an explosive device concealed in checked baggage, killing all 329 people on board.

British Airways Flight 5390 — The Windscreen and the Captain Who Nearly Left

The captain of British Airways Flight 5390 was sucked partially out of the aircraft through the forward windscreen at 23,000 feet and held there — by cabin air pressure and by cabin crew grasping his legs — for twenty-two minutes at 300 knots and minus seventeen degrees Celsius. The first officer declared an emergency, made
