Happened today. Remember it well not being that far away. When the the engine fell apart tearing up the all the hydraulics.

Miami, Florida - United States...
I thought it was this flight that probably started the definite demise of the DC-10 (remembered it very well, I lived there). My respect for those who have perished on that flight:

American Airlines Flight 191 (circa 1979)

American Airlines Flight 191 was a regularly scheduled passenger flight operated by American Airlines from O'Hare International Airport in Chicago to Los Angeles International Airport. A McDonnell Douglas DC-10-10 used for this flight on May 25, 1979, crashed moments after takeoff from Chicago. All 258 passengers and 13 crew on board were killed, along with two people on the ground. It is the deadliest aviation accident to have occurred in the United States.

Investigators found that as the jet was beginning its takeoff rotation, engine number one, on the left wing, separated and flipped over the top of the wing. As the engine separated from the aircraft it severed hydraulic lines that locked the wing's leading edge slats in place and damaged a three-foot section of the left wing's leading edge. Aerodynamic forces acting on the wing resulted in an uncommanded retraction of the outboard slats. As the jet began to climb, the damaged left wing, with no engine, produced far less lift (stalled) than the right wing, with its slats still deployed and its engine running at full takeoff speed. The extremely disrupted and unbalanced aerodynamics of the aircraft caused it to roll abruptly to the left until it was partially inverted, reaching a bank angle of 112 degrees, before crashing in an open field by a trailer park near the end of the runway. The engine separation was attributed to damage to the pylon structure holding the engine to the wing, caused by faulty maintenance procedures at American Airlines.

That pic is impressive and scary at the same time!

Contributing to the cause of the accident were the vulnerability of the design of the pylon attach points to maintenance damage


Right, it's a design flaw if maintenance isn't performed IAW manufacturer guidelines and something breaks. Blow the engine in your car because the Jiffy Lube guy overtorqued the drain plug, causing the threads to strip and the plug to vibrate out, and it's the automaker's fault for using threaded parts that can strip.

These United States of America
A very tense read for me. I'm sad for those lost. I'm always amazed hearing about these stories where so many people pull together in an intense and stressful situation and work together to do the best they can and to do as much as they can in such a short, concentrated period of time.

I'm pretty sure the TV series Mayday had a episode on both those accidents.

Also Turkish Airlines Flight 981.

The MD11 is still flying


There was only 16 squadrons of RAF fighters that used 100 octane during the BoB.
The Fw190A could not fly with the outer cannon removed.
There was no Fw190A-8s flying with the JGs in 1945.
