Some of the Velocity incident sounds familiar - but I thought the one I read about was spinning - It has been a while and I am approaching senility
Funny tho -- the Jim Moser involvement .
Jim had a Bucker Jungmann which he modified extensively -called the Super mann
he sent me stacks of photos of it -which I used in doing some models for the TOC in 1989- but not used till 1990.
I still have one -which was flown to 2nd place by friend S Rojecki.
