Yeah, the Nth-metal belt buckles do the lifting; the wings are for movement and maneuverability. There are many instances when the Hawks flap their wings to knock crooks off their feet, extinguish fires, and other silly stuff.

In the real world, until relatively recently, I didn't realize that garage door openers depended on a huge spring to counter-balance nearly all the door's weight, and the small electric motor only provided a very small amount of lift to raise the door.
