It is apparent from the following excerpts, taken
from logs maintained by ground personnel on November 24,
1971, that the hijacker exited the airplane at 8:11 p.m.
local time.
---
When the hijacker jumped, the air stairs were
forced closed causing an increase in air pressure similar
to shutting a car door with the windows up. As this pressure
increase occurred the co-pilot turned to look at the cabin
rate of climb meter and in doing so his communications ear
plug was pulled from his ear.
---
The co-pilot's comments at this time were being
recorded on a tape recorder which had previously been started
on a time standard signal. Through careful play back and
sequencing, the time of the pressure oscillation caused by
the air stairs closing after Unsub departed was determined
to be 8:11 p.m. local time.
