Lear jets are sooooooo 1970's pedestrian in the 21st century.
I can in all seriousness go test-fly a Citation today at their dealership only 7 miles from my house if I wanted to buy one. For that matter, Trump's personal 757 is sitting only 6 miles away for about a year now, apparently having an engine overhaul. There was also some sheik's personal 747 sitting over there for years sans an engine or two, which would be my choice for a personal jet since the Concorde's air worthiness certificates were terminated.....
