I'm not familiar with TF mythos, but its always struck me that the Autobot's inability to fly is a severe disadvantage (If Ironhie & Co. could fly, they'd have saved Prime from death in the forest fight). How do the Autobots move around, bar military cargo planes? Space bridges? And how do they leave Earth? I see SS and Meg just jetting off to Outer Space? Can the Autobots do that?
