First time I saw a Harrier was at Keesler AFB, MS. I was in my dorm room, about 50 yards from the end of the flight line where the planes would leave the runway. I was looking out my window, on the 3rd floor, and saw this jet coming down the runway about 50' off the deck. I could see it slowing down, but not loosing altitude. I thought, this jet is gonna stall and crash! When it got to the end of the runway, it hovered, turned 180 degrees, angled upward and took off like an arrow from a bow. I didn't have a clue jets were capable of doing that! WoW!! I think this was around 1974 or so.
