Watch NASA dummies crash test flying and falling vehicles

This week, NASA’s Langley Research Center published a video of the crash-test-dummies whose horrifying accidents make air and space travel safer for their human counterparts.
The dummies keep humans safer by giving scientists key data about whether bodies bend or break under different crash conditions. So they’re outfitted with sensors and instruments, and can vary in size from 105 to 220 pounds to simulate a range adult human bodies.Then, the dummies are strapped into the seats of
