Cooper told Tina that he had some pills for the crew if they started getting tired.
Is there some way to verify whether this actually happened? Is this in a 302 somewhere?
This strikes me as exceptionally odd and naive if it's true. Obviously the crew is not going to ingest a pill from a skyjacker while commanding an airliner. If Cooper actually considered this a possibility it is remarkably bizarre. It appears to run contrary to what we know about Cooper. I'm inclined to think this is not accurate.
See Richard T. Tosaw's book, "D.B. Cooper - Dead or Alive", ISBN 0-9609016-1-2, 1984, page 31. The very last sentence at the bottom of that page reads as follows:
"Tina told Cooper that she was concerned about the crew getting tired on the long trip, but Cooper told her, 'Don't worry, I've got some pills that will keep them awake.' "
This statement was made during the time the airliner was on the ground in Seattle. And I don't remember seeing it anywhere else.
Tosaw was a California lawyer who had been an FBI agent for five years before setting up his legal practice. He spent a significant amount of money searching in the Columbia River just off shore from Tina Bar. He interviewed many of the principals in the matter including the Ingram family and apparently talked to Tina at length.
I recommend that everyone get a copy of this book, if possible, since it contains things that apparently were not included in the FBI investigation paper work.
