Failure - Interactions
"Central to the drama is the persisting dispute over why the incident occurred in the first place.
What is undisputed is that the plane was thrown into its spiraling dive by a slat . . . ."
[Dick Witkin's review of the CBS Reports TV-documentary, New York Times, July 14, 1983, p C22.]
This "THUD" noise, or
"a popping sound"
were mentioned in several of the earliest reports from crew and pax describing their INITIAL upset.
[These sounds are typical of
engine compressor-stall,
during beta (sideslip angle).]
"A buffeting and
a THUD noise . . ."
