Big dollars.... I remember at the big Geneseo airshow... back when it was Wings of Eagles- there was a two plane aerobatic team flying Fouga jets there one year. Those guys were absolutely nuts, or so it seemed at the time. Wish I could remember the details.
It was different to see a jet fly off a grass runway...
Have you been to the airshows lately? Smaller, but they've got the same character that the Wings of Eagles show started out with. You can touch every plane.
