I recently had the good fortune of seeing a C-17 in flight. The Air Force sends it around apparently as a sometime recruiting tool and I would guess it to be as effective as any fighter jet. It's crew certainly looked pleased warming it up, then wheeling it out backwards on to the tarmac (four fully reversible turbofan engines with up to 43,000 lbf).
Here it is performing a few tricky moves a plane of its size has no business performing. Gives me some hope for us people of a certain size. Maybe we've all got a few dance moves up our sleeves as well, though I know I'm nowhere near so graceful as this machine.
