"You need to shoot out of here at top speed, just like a catapult!"

"A catapult?"

"Humans use them to launch planes off ships."

"All you have to do is step on the platform, and then—blam! You're in the stratosphere!"

"Look kid, I don't know what the heck..."

"No, Jetfire, I think the kid's got the right idea."

"What idea?!"

"The catapult thing! You could reach maximum velocity before you leave the base! Without using extra energon."

"Really? Well, why didn't you say that in the first place?"

"We did!"
