Your Reply: HTML is ON UBB Code is ON Smilies Legend	[QUOTE]Originally posted by LM-12: [B]LM ascent stage liftoff on Apollo 11: <BLOCKQUOTE>[i]ALDRIN: Lift-off, or at ignition, we waited until the last 2 or 3 seconds, or almost simultaneously, Neil depressed the abort stage and threw the engine arm switch to ascent and I proceeded on the computer. It might have been a second after the T-zero that any motion was detected. There was, as I recall, an appreciable bang of the PYRO's and a fair amount of debris that was tossed out at the same time that we did detect first motion. It was a fairly smooth onset of lifting force. There wasn't any jolt to it. Yaw started gradually; it was not abrupt either starting or ending. As a matter of fact, I really didn't notice it. I was looking more at some of the gages and the altitude rate, both in the PGNS and the AGS. It seemed to take quite a while before we accumulated 40 or 50 feet per second.[/i]<BLOCKQUOTE> [/B][/QUOTE]
