I had 60 hours of flying time here and in January of 1943 was graduated from primary training school.
It had less than ten hours' flying time, and he didn't want it wrecked by having a careless winchman bash it against something.
She staked all on present occupation and the truth of flying time.
At first we were far too busy learning the rudiments of combat to keep an accurate record of flying time.
Birds kept caged past the flying time never learn to fly well.
The only possible way of keeping pace with flying time in the army, is by writing a diary.
