Once at Dallas Love Field I was on board a Braniff 727 which made what seemed to me to be a very hard stop during an aborted takeoff due to somebody getting in the way. We turned around, went back and started the next attempted/successful takeoff right away. I had just been reading a B-52 manual which put a lot of emphasis on procedures for brake cooling after an abort. Had to wonder what would have happened if we had to do a second abort. Brake fires can be bad news.
Love Field is the reason I no longer fly (except maybe an emergency). Anyway, in 1969 I was returning from Tampa and seated on a window seat next to two NASA pilots. I enjoyed the chat and when we came in to land, the plane tilted drastically to port (my side).
I looked out and could see the shadow from the wing just under the wing. We were inches (2-4?) from scraping.
The pilot got the hulk back under control and brought her in. At de-planing? the pilot came out and he was white as a sheet. Both NASA pilots said that was as close to a crash as they had ever been.
I was too ignorant of flying to appreciate the danger but time has made the situation sink in.
