Unfortunately, he could not realistically land and also remain alive.
A group of students from the University of Leicester have run the numbers and determined that the wingspan of Bruce Nolan’s Batman’s rigid cape is large enough that he could fly. They also determined that the mechanism of the specially-designed cape would allow it to function similarly to a wingsuit.
These revelations were published in a paper hilariously titled, Trajectory of a Falling Batman.
The scientists confirmed that the wingsuit-like properties of the cape (which is about half the width of a hang glider) would allow Batman to glide 1,148 feet from a height of 492 feet. Realistically, this would allow him to jump off a tall building and glide around, looking for crime, with no problem, provided he didn’t run into any buildings.
And then he would hit the ground with such force that he would be lucky to remain alive. It would be the equivalent of being hit by a car going 50 miles per hour.
The team suggested that the Dark Knight might want to consider jet propulsion, a parachute, a bigger cape, or piles of strategically-placed boxes.
