Failure - Interactions
This historic documentary,
"The Plane that Fell from the Sky",
was not available for decades
from 1980's into the 2000's.
Suddenly it became easily viewed, on YouTube.
Then, in 2018, just as suddenly,
this video was blocked on YouTube.
Paul and Holly Fine (producers) :
their work is available on Vimeo
"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
during beta (sideslip angle).]
