I WANT ONE
They are cool!
But why not use a helicopter...?
Can't land on wonky ground?
I doubt if jet-boy can either in reality... And he certainly won't be carrying loadsamedical stuff... or a stretcher or be able to recover the victim.
But a helicopter can lower a paramedic and stretcher to the victim and winch them both up again after...
I'd be willing to bet this never gets off the ground...
