This was actually my first thought too.
Very cool though.
Out of curiosity, why does the aircraft only pull one gear up at a time? I imagine it's the way the hydraulics are hooked up?
Possibly. Semi-related, but as a Engineer/Operator on a Fire Engine I know that hydraulic tools (jaws of life, spreaders, winches, sawzalls) that are hydraulically operated can only be operated one at a time.
