Many years ago I dated a girl who's mother told me that she met Igor many times in the late 40's early 50's and he told her a story that he was visiting one of his employees in the hospital and as luck would have it there was a helicopter test pilot (working for another company) who was in the same ward or room. The test pilot had an engine failure and crashed, when Igor asked him why he didn't autorotate the test pilot looked at him and said "whats that"
Has anyone else ever heard that story or was I led up the garden path?
