Mil Mi-12 "Homer" Is World's Biggest Helicopter, Looks as Dumb as Simpson

We missed the Mil Mi-12 in our roundup of crazy Soviet aircraft. The "Homer," as NATO calls it, is the biggest helicopter in the world at 220ft from blade to blade, as wide as a Boeing 747's.This beast was able to lift 88,636 pounds to 7,398 feet, which was another world record. Sadly, it was never mass produced because it was extremely difficult to fly.
