The Soviet-designed An-225 -- the world's largest operational aircraft -- was originally designed to transport the USSR's space shuttle. That program is long gone, but one An-225 just broke the world record for the heaviest airlift of a single object. It transported a 53 foot long, 187.6 ton generator from Germany to Armenia on August 11. Because the An-225 can (hypoethetically) transport any object up to 33 feet wide, 230 feet long, and under 275 tons, the generator's size and weight didn't cause any problems.
