[REDACTED] put
the aircraft in the same flight configuration as the
hijacker had directed, at which time Air Force personnel
allowed the weighted sled to fall from the end of the stairs.
The reaction in the airplane was instantaneous and was
described by [REDACTED] as being the same reaction
that they had in the airplane when they believed the hijacker
jumped.
---
As a result, [REDACTED] has now taken this
information, together with some refined data given to him
by the Air Force, and has identified an area near Highland,
Washington, where it is believed the hijacker jumped.

The employees of Northwest not only spent considerable
time on this project, but [REDACTED] had to arrange for the
airplane to be taken from the flight line for a day and one-half
so it could be accomplished. The representatives of Northwest,
particularly [REDACTED] have been extremely helpful during
this entire investigation and in view of this extended effort
on their part, it is suggested that the Bureau may desire to
address a letter to [REDACTED] Northwest
Airlines, expressing the Bureau's appreciation.
