Stratosphere

When a unit of Autobots needs to get somewhere fast, they turn to Stratosphere. His cargo plane mode can transport an entire team half way around the globe and then supply high-altitude covering fire when they get there. In the air, he is virtually unbeatable, and he knows it; Stratosphere thinks he can take on just about any challenge all on his lonesome, and this becomes a distinct problem when the threat is on the ground, where his combat abilities are no great shakes. As a consequence, he doesn't like to spend a lot of time on terra firma, preferring to reign supreme in the sky for as long as possible.
