Post your favorite manmade air-capable vehicle (or vehicles) and why you like it (or them). This includes all planes, helicopters, balloons, blimps, and anything else that can go airborne for a sustained period of time. They can be from any time period in history.
I think one of my most favorite is the SR-71 Blackbird.
It isn't much more than a high-altitude recon jet, but damn it's purdy.
