Okay, it's not Sharknado, but it
is a bigger helicopter. It's a bike-icopter. It's a helicycle!
Quoting from the article at
This Is Colossal: "The Igor I. Sikorsky Human Powered Helicopter Competition was established in 1980... To win the prize a team of engineers would have to build a helicopter powered solely by a human that would achieve a flight duration of 60 seconds, reach an altitude of 3 meters (9.8 ft), while remaining in a 10 meter (32.8 ft) square."
It took 33 years, but a team from the University of Toronto finally did it. Go, Canada!
