one o'clock
At seven o'clock , all preparations having been made , Norman turned in for a few hours ' sleep . Colonel Howell devoted some time to his private arrangements and spent the remainder of the evening discussing the flight with the other occupants of the cabin . Norman being sound asleep at twelve o'clock , the others agreed not to arouse him for another hour , considering the work he had done that day . But at one o'clock new activity began . A match was again applied to the gas well and the monoplane was whirled out into the spectacular illumination . There could be only a brief handshake all around . Then , without a slip , the monoplane was off in the light of the waning moon .
