“All big jets fly IFR. Not sure if a Gulfstream fits this or not. I am sure the insurance cos. have something to say about it.”
No they do not. There are times even the big iron flys vfr, no flight plan.
Huh. I had no idea airliners could fly VFR no flight plan. Could a 747 or 737 do it, and if so, what kinds of trips...are the limited to a certain distance or something?
