Batman > Physics?

Where would Bruce Wayne be without the batsuit’s ubiquitous slick cape? Alive and well, according to physicists at the University of Leicester, who have revealed that the impact of the hero’s plunge back to Earth after a little lofty cape-gliding would be the equivalent of being hit by a car at 50 mph.

Overall, depending on your standards, Batman seems to do pretty well in a reality check. The "memory cloth" cape that becomes rigid as a current passes through it was deemed a possible means of flight. But it's not the flying that gets you; it's the landing. The students mathematically calculated what his impact would look like, and it's not pretty. Roughly, it would be about the same as getting hit by a car going 50 mph.

The paper does admit that variations of the angle of the glide were not taken into account, and could contribute to a safe landing.  

Interesting subject for a thesis, not sure it is going to help solve any crimes though.  Rock on Caped Crusader :o).
