Human-powered flight human-powered aircraft require a pilot to pedal, as in a bicycle, and produce a sustained power output of about 0.30 hp. the gossamer albatross flew across the english channel on june 12, 1979, in 2 h 49 min.

how many snickers candy bars (280 cal per bar) would the pilot have to consume to be "fueled up" for the flight? note: the nutritional calorie, 1 cal, is equivalent to 1000 calories (1000 cal) as defined in physics. in addition, the conversion factor between calories and joules is as follows: 1cal = 1000 cal = 1kcal = 4186 j.
