"One critic said that usually I was pretty much to be relied on, but when I made a picture called Only Angels Have Wings, now that was just too much for anybody to believe. I wrote him a letter and said that—I kept a copy of this letter and I’m thinking of publishing this letter—every single thing in that picture was absolutely true, there wasn’t anything I invented. I invented how to use it. I got back a very nice letter.

And the only thing I couldn’t use was the fact that the fellow with the burnt face got up and said, “A year ago tonight you were married. You went to bed about ten minutes to two. You got up at two o’clock. There was a pause of about 15 minutes, then you repeated this thing,” and the girl said, “Damn you, you were peeking!” And they brought out a German machine used to keep the hours on flying; and it recorded when the motor started on a scroll, it recorded the takeoff run and recorded in the air, change of altitude, and landing bumps, so that they had a complete record of the time. And he’d hung it under their bed. Instead of being angry, the girl was so pleased and so proud of it, she put it up over the fireplace…."
