Re: What-If 0113: "Visit Every State"

Instead of a lengthy refueling, you can just swap planes. Of course you should first decelerate the fighter to a speed at which the pilot(s) can "safely" get out and hop to the other one. It works in BF2 , so I expect it to work in real life. :D Good luck pulling that off at Mach 3. I bel...

One consideration is that the refuel time may be a little longer than I estimated; the SR-71 is a much bigger bird than the F-14.
