Behold, the largest plane in the US Air Force

At 222 feet across, almost 300 feet in length, and 65 feet above the ground, Lockheed Martin's C-5 Galaxy is the largest transport aircraft in the US Air Force.

With a cargo hull 121 feet long and 19 feet across, the C-5 is a flying warehouse that can carry a combat-ready military unit or deliver necessary supplies anywhere in the world.

The C-5 has a cargo capacity of 142 tons, the equivalent of carrying two M1A1 Abrams tanks, 6 greyhound buses, or 25,844,746 ping pong balls.

In the slides below, see just how awesome the C-5's carrying capacity is.
