Know of one incident where the pilot of a '47 G2 contemplated GR.
what happened was he heard a bang and everytime he wound throttle on or off it starting shaking big time. He figured that he had lost a drag brace bolt.
So with care he landed, screwed down the frictions, didn't want to sit in it to shut it down ran it down slowly to low idle, got out, pulled the fuel shut off and - cut - to use an OZ outback term.
Dammit the machine stopped and ran down OK, we figured that as Nick says the deceleration was equal both sides.
The story didn't end there, he who was extremely popular and laid back sort of a dude now passed on long time, was also known as a make do expert and base was a quite aways distant, 2.5 hours or so. So our intrepid pilot wired the drag brace to the blade with a cobb and co hitch with two strands of number eight wire and flew home.
This being a friday afternoon quite late, yeah something else he was noted for, so he rings the engineer about sunday afternoon and said that he had to go out daylight tomorrow could he do a daily on the machine -had a small problem with that head thaang on top friday -, or words to that effect.
I think the engineer still wakes up in the middle of the night thinking about it.
