When Hot Shot was temporarily blinded while driving on a hazardous space bridge, Red Alert ordered Coby Hansen to assume control via synchro-control. Coby used set of controls built into a column in the Autobot base, guiding Hot Shot via a 3rd person overhead sensor view until he as able to resume proper control. Starscream
