Nice info, quasi. The F-117 Stealth "Fighter" (which is not really a fighter, but a light bomber) is also highly unstable in flight and would not be practical without advanced computerized flight stabilization. The F-117's inherent instability caused pilots to give it the nickname "Wobbly Goblin."

If you watch an F-117 in flight, you can sometimes see large panels pop up and lay back down -- just like the panels on NASCAR race cars which pop up if the car spins out of control and starts skidding backwards.

I never understood the need for the B-2 when, for the same price, you can build dozens of F-117s that are capable of doing the same job. One lucky shot on a B-2 would cost us $2 billion, while it would take dozens of lucky shots on F-117s to cost us the same amount. It just doesn't seem to add up. But both planes are cool.
