Popular Quotes

In the1969 mission to the moon, the lunar module control computer flashed a Program Alarm warning message, and the Mission Control officer Steve Bates, with less than 30 seconds to go, had to make a decision whether to abort the module landing or continue. He spoke to Garman, who concluded that since the message did not repeat, that the message was most likely a spurious message—a false alarm. German told him to go ahead when most others wanted to abort. As Garman was the most familiar staff member with the software, Bates followed his lead and continued the landing. Garman was right and he became known as “The Man who saved the Moon Landing”.
