Explore the physics of how jetpacks fly, and discover the technology that allows pilots to maneuver the engines. -- In 1961, Yuri Gagarin piloted a spacecraft in humanity’s first manned space flight. A week later, Bell Aerosystems debuted a gas-powered rocket pack that could fly 35 meters in 13 seconds. Unfortunately, engineers knew this short flight was all the rocket pack could muster. So why was a massive spacecraft easier to send flying than a single pilot? Richard Browning investigates. Lesson by Richard Browning and Gravity Industries, directed by Mitch Hearn and Lisa Vertudaches.
