A Private Pilot had installed a video camera days before he had an emergency (pure "luck" - if you will). He took off from his home airport and lost a cylinder below 'Pattern altitude' (1000ft above ground). FAA regulations teach you that, if you lose an engine on take off, you choose a road, field or highway straight of your course. Turning back "always" results in too low of a speed to keep lift. This guy was lucky since; he owned the airplane and was familiar with the airport. flash.aopa.org/asf/pilotstories/impossibleturn/ |

Scary!  Question? In 1979 a American Airlines DC10 took off from O'Hare Airport on route to Los Angeles. Someone was videotaping out side the airport. You can see this plane as it cleared the runway and all of a sudden a "Object" falls from below the right wing.It was an engine . The plane came down fast and exploded killing everyone on board. Now to me that would be an aborted takeoff. Can you explain to me why it crashed like that?.  |

Do you have a specific link to this incident (since it was so far back)?
My guess, based on your explanation is that the truss structure that holds the engine to the frame broke loose, removing the engine.
With a drop from 100% to 75% power on take off (the second most critical time - next to landing).
Reaction time is delayed in a jet like that.
1) You can't see the engines.
2) You have 50+ gauges in front of you.
3) You have 150,000lbs of dampening weight behind you to delay everything even further.
They figure that, in a Cessna 172, it takes 8-12 seconds from an engine failure to the pilot's first reaction.
In 8-12 seconds you can drop 175 feet.
In a complex aircraft like a DC10; 8-12 seconds is critical/fatal.

The NTSB site is taking a dump on me right now but, from what it looks like; the pylon (connection) failed under the most extreme conditions that an airframe is under during flight.
It would be like a tire blowing out on you during a 90 degree turn at 80MPH.
This is why we (GA aircraft) do a "run-up" (revving the engine on the ramp) before take off.
That way, we make sure (hopefully) that the engine isn't going to exit, stage left, on take off.

Yeah, I read the article and you are correct. That is just what happened . At the time they did not require pylon check then . They do know because of this. I actually saw the crime scene pictures of this crash.Torsos roasted .  |

One thing they tell us in flight school: Learn from others' mistakes instead of finding them out for yourself. This is a good example.  |

Yep....So is Megan's law. Amber Alerts and Code Adams. Sad that it takes loss of life to catch on. |

A "bad" example is the Brady Law.
Making law abiding citizens conform to restrictions based on criminal activities is senseless and distructive.
