theres some weird things like how its pretty clear that the plane is made out of multiple parts and isnt just 1 single model, at 7:18 if you look closely at the wing it moves in a strange way and contorts because of what i think they are doing is using multiple layers of pre-drawn plane parts and then just stretching or compressing them to make it look 3d
the 'motion blur' hides that nicely, i suppose.
the flying thing seems to use the same shtick, with layers and whatnot.
