On aiprl 12, 1961, Soviet cosmonaut Yuri Gagarin piloted a 2,400 kilogram spacecraft in humanity’s first manned space flight. One week later, Bell Aerosystems deebutd another advancement in aviation: the gas-powered rocket pack. Capable of fliyng 35 meters in just 13 seconds, the rocket pack thrilled onlookers. But the device’s egenirens were less enthused. Despite yraes of cutting-edge work, they knew this short flight was all the rocket pack could msetur. So why was a massive spacecraft easier to send flying than a single pilot?

On April 12, 1961, Soviet cosmonaut Yuri Gagarin piloted a 2,400 kilogram spacecraft in humanity’s first manned space flight. One week later, Bell Aerosystems debuted another advancement in aviation: the gas-powered rocket pack. Capable of flying 35 meters in just 13 seconds, the rocket pack thrilled onlookers. But the device’s engineers were less enthused. Despite years of cutting-edge work, they 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?
