The Super Guppy

Gotta be one of the biggest planes ever built, especially for a prop. Anyone tried building it for FS yet?

The Super Guppy, designated 377SG-201, has a cargo compartment that is 25 feet tall, 25 feet wide and 111 feet long. It can carry a maximum payload of more than 26 tons. The aircraft has unique hinged nose that can open more than 200 degrees, allowing large pieces of cargo to be loaded and unloaded from the front.
