No, I didn't land on all seven continents in the Lear 45. I just went around the world with it once. I started in Colorado and headed East up to Nova Scotia and then to Greenland, Iceland, Scotland, down to London, into Europe, Ukraine, a part of Russia, over the Caspian Sea to some *stans*, India, Nepal, South East Asia, Guam, Wake Island, Midway, Hawaii and then had to cheat with the fuel going from Hawaii to California, From California went to Vegas and back to Colorado. That was one of five trips around the world.
The other trips were all in my F-22 and it is with the F-22 I touched all seven continents. In Antarctica I landed at Mcmurdo. In the F-22 I typically fly at FL500 @ an unrealistic cruise of mach 2.35 which is around 1,500 MPH ground speed. I average about 500 miles per day and this is about an hour with take off, cruise, approach and landing. I can't fly longer than that because it gets awfully boring despite playing Amazon music.
