What I'd like answered is a question regarding how they navigate. It's all easy to fly a remote copter by remote control and make it go left, right, forward, back, up and down - but making them literally
snap to a point in 3D space is incredible. Even more so is making several snap to points adjacent within that 3D space. How do they know where they are from millisecond to millisecond in relation to the ground and each other? They have to navigate, otherwise they'd never be able to accurately fly in any sort of formation. I'd hard a guess and say it's controlled optically, and I also guess that they say it somewhere on the site. Mebbe I should stop right here and go and have a look...
