Here's an amazing video. Two quadracopters toss a pole back and forth:
What's a quadracopter? A small flying vehicle propelled by four spinning propellers. Once one quadracopter has tossed the pole, the other one has 0.65 seconds to calculate the pole's trajectory and get itself in place to make the catch, after which it must, of course, balance the pole.
