"Mr. George Harrison, Northwest Airlines(NWA), Flight Operations, Seattle-Tacoma International Airport, (SeaTac) advised that he talked with Mr. Barry Halstead of Pacific Aviation at Boeing Field, Seattle, in order to secure parachutes . . . "
The above captures the times back in the 60s and 70s, and how things commonly worked even in large programs and corporations. Things and operations could be remarkably informal, personal, involving a few people in strategic offices ... It sometimes seemed like a small club functioning. It was like this in large corporations and in large institutions .... on any given day one or two people could be handling, directing, and dealing with very large problems, making calls, receiving calls ...
George Harrison was obviously one such personal in NWO operations who was activated to perform multiple tasks dealing with the Cooper hijacking. Actions were being set into motion, decisions being made, people being tasked to 'do this-do that' .... perhaps without moment-by-moment records being kept.
It was all very personal for those involved!
