rotorboater;
I have a share in a JP4, the bills aren't small, but the smile factor while flying is huge. The bills for a harrier would be earth shattering (I did the research, it was a question the feds asked) The level of experience we have to provide both for the feds and our insurers on the JP are quite large, the requirements for the harrier were the stuff of NASA selection!
Thats why I only do 20 hours PA in the JP as opposed to 150 in my YAK 52.
