Yes, your associate is correct. I read in one of the trade pubs last month that the guy who was touring the airshow circuit in the Beech-18 is painting up a Lear 23 in black (can you say "pro-seal") and red, and is going to tour the airshow circuit this year. I hope the crowds have plenty of earplugs for when those CJ-610s go screaming by...
I was watching JAG one evening and they had a Learjet in the story line. Short form: The main character "looped it to a landing."
I thought that it was rather, uh, extraordinary and a little far-fetched. Made a comment to a former DO about the hilarious episode. Joke was on me. Apparently Learjet (back in the day) would roll the aircraft and then "loop it to a landing" during a demonstration. Unfortunately someone died during a demonstration and the aerobatics were deleted.
I really do trust this DO not to spoof on me, so anyone else ever hear of this??
