At first I thought 'big deal'. They've had swing-wing planes since the 60's I think.
But then :
it relies on the properties of a temperature-activated material called shape memory alloy instead. Upon being heated, the alloy activates a twisting motion in the tubes serving as the wings' actuator, moving the wings' outer portion up to 70 degrees upwards or downwards.

So, ok, I'm impressed.
