Watch a Speeding Bullet Fly by a Propeller in Slow Motion
Gavin and Daniel of The Slow-Mo Guys wanted to figure out how WWI pilots fired their guns while simultaneously flying a plane. How did these pilots manage not to hit their own propellers? In true Slow-Mo Guys fashion, everything is filmed at high speed so you don't miss a single detail.
And of course, Gav and Dan removed the sync from the system and saw how well the propeller could turn out after a round of fire. The propeller gets several holes, but surprisingly fewer than we predicted.
