I wasn’t alive in 1971, but I guess you were.
How are you so familiar with airline ticketing operations?
Simple. I did quite a bit of traveling on the airlines for both professional business and personal business in the 1960s and 1970s. In fact, I was traveling on the airlines for personal reasons east of the Mississippi River on the very night that Cooper hijacked the airliner in the Pacific Northwest.
"personal reason eh" ... do you happen to wear clip-on ties?
I have never worn a clip-on tie. But read below.
FULL DISCLOSURE: I spent several years in Washington State in the late WW2 era. During that time, I saw one of those Japanese balloon bombs fly right over my head but a couple of P-38s were circling it and reportedly shot it down when it got to an uninhabited area a few miles east of the Columbia River. After that time frame, my next visit to Washington state was in 1975 to attend a family get-together.
My limited amount of parachuting experience ended in the mid-1960s. No parachuting in the 1970s or later.
I spent most of the 1960s and 1970s working east of the Mississippi River. I did spend a significant amount of time in that era working in a remote desert area somewhere but can't remember where it was.
I am not D.B. Cooper.
