Biggest 747 ever built takes its maiden flight
The biggest plane ever built in the U.S. just took to the air. This Boeing 747-8 freighter prototype flew its maiden test flight, proving that a plane that's even longer than that huge Airbus A380 can actually fly.

After Boeing cranks out a few cargo versions, this plane that weighs about as much as 5,100 fat American guys will be built in a passenger version. Those lucky enough to have a window seat will be able to peer out of peepholes that are 8% larger than those on today's 747s.

President Obama might soon be flying in one too. Boeing is urging the Air Force to get rid of its old 747 VC25s and instead use one of these behemoths as Air Force One.
