How long did that pre-flight prep last? From the first step to actually being in the air?I'll try to respond to a few of the posts and answer any other questions that I can on an internet forum. I flew the U-2 from 2010 until my retirement last year, total of 1147 flight hours. Here's a video that Air Force public affairs did of a mission I flew over Iraq/Syria in the summer of 2016. And yes, I probably checked HROT Off Topic when I got back to my room that evening
