Behold, the largest plane in the US Air Force

The engine alone is more than 7 feet across.

Even large helicopters are tiny compared to the C-5.

To ease on and off loading, the C-5 opens from the nose and the tail end.

With four massive engines that each produce the force of about 800 cars, the C-5 sounds amazing. (Sound starts at around the 0:30 mark in the below video)

Chinook helicopters fit with ease.

Hauling an A-10 is no problem.

Here comes the M1 Abrams.

More than 266,000 pounds of cargo and armored vehicles are seen loaded into the C-5 in Afghanistan.

Here the C-5 unloads an 81 foot boat for the Navy.

The C-130 is a big plane in its own right, but its fuselage fits easily inside the galaxy.

In times of trouble, when aide is needed on a huge scale, the C-5 is a welcome sight.
