AE Systems tested a new ejection seat that will be deployed on over 3,000 F-35 Lightning II combat jets around the world, using a 600-mph rocket car, a battery of sensors and one lucky mannequin. They captured it on video — but don't blink or you'll miss it. The test took place in early April. Though the entire emergency escape operation, from handle pull to parachute deployment, typically takes only three seconds, the team took up to 900,000 measurements per second.
