The Price of Flying

In superhero movies, there are always scenes where the heroes fly. This technology has been a research subject for scientists. Recently someone put on the Flyboard air vehicle, powered by jet engines carried in a backpack, and successfully crossed the English Channel. Besides refueling halfway through the journey with another backpack being the biggest challenge, during the flight one also experiences pain from muscle fatigue and harm brought on by resistance from strong winds. Everyone can now understand that in the real world, one has to pay a big price in order to become a superhero by putting on armor.
