Optimus Prime is, so far, the only Autobot flier these films have shown. And he's done it with about four different sets of flight gear: - the parachutes in ROTF Shanghai - a jetpack from Jetfire's parts - the flight tech in his DOTM trailer - and his built-in rockets in AOE Which was your favourite? For me it's the Jetfire jetpack. It's a great homage to ARMADA, and it's touching that Jetfire gave up his life to assist Optimus. The DOTM flight gear was awesome too, it's my runner-up. But then that trailer was an amazing bit of tech.
