One day I was starting up an engine with my strap dangling down, one of the other pilots walked over and suggested I flip it around so it was on my back. Sounded good to me and I have been in the habit of flipping it around ever sense, that was a lot of years ago. Another one of those things I don't need to think about, it just happens. Habits are great if they are good ones. I never think about moving a stick, I just think I want the plane to do something and it happens. The tray guys all wear the straps but they don't dangle, the plane is fired up and then the pilot connects the two clips. Funny, I never fly my own planes without a strap but when I fly someone Else's I never use one. Nothing to dwell on, it's just one of those things that I never question and I just thought about now.
