Donatella Ricci (sp) of Italy is the world altitude holder at the moment I believe. She flew a Magni 914 to 27,7?? ft.
Then there was the Little Wing guy (Ron Heron??) at 27,??? and before that, my hangarmate, Dr. Bill Clem who flew
to 24,724 ft. in an open frame 914 Dominator. (I hope I have the order correct)...
During his record attempt, Bill heard a radio conversation go something like this....
'United 456 Heavy, Miami Control; Be advised traffic 9
'clock, 4 miles passing through 24K is an experimental gyrocopter.'
United 456 Heavy..."Say What???"
I have been to 12K myself but that's only 6500' AGL here as my
base runway is 5512' AGL. I can only imagine the exhilaration each of them must have felt. As mike pointed out,
the seat definitely gets thinner as the pucker factor increases exponentially. I felt like I was flying on the business end
of a razor blade without any shaving cream!!
