American Flight 191 - Recovery Procedure

I was speaking about ANOTHER accident that had been asked
about. I was speaking about the Sioux City accident. I had
already addressed the 191 slat retract.

Are you saying anything you shouldn't?

Yes, a DC-10 at Tulsa had both wing mounted engines fail
after sucking up about 10,000 sparrows. Came around on just
the tail engine.

The problem with flight 191 was that the crew did not know
the slat had retracted. Since lift varies by the sq.root of
the speed, the wing would not be stalled at V2, but with the
slat retracted, the effect was greater than the combined
effect of rudder and aileron anti-roll command. At 300 feet
they just wasn't time to figure it out.

Running both hydralic lines (allowing the slats to retract) within
inches of eash other was perhaps a questional decision.

All the time, why?

It was OK on the DC-9 and nobody considered the difference
on the DC-10. Yes it was a bad design as was not using
hydraulic fuses and not having essential power as is now
required on Part 25, perhaps because of what was learned
from 191.

It's common and public knowledge that one of NORAD's responsibilities
is to monitor missle launches.

Yes, but the exact monitoring capabilities of satellites may not be
public knowledge (although they aren't necessarily always classified,
either).
