Watch NASA Plane Fold Its Wings Mid-Flight

We've been hearing for a few years that plane designers are trying to use NiTiNOL to change the angle of the wings or of the fins (my terms, probably not the term of the designers) behind the jet engines.

Now, it looks like NASA might've been successful in adjusting the wing angle using a memory alloy.

And, if you were curious about the size of the plan we see above, here's a longer video with a little more context and without the voice-over.
