I was thinking along the lines of this:
1.She digs her blades firmly into the door.
2. She holds onto the chains in a relatively close position to the door.
3. She drop kicks the door, and theoretically, with enough force, it should fling her forward using forward momentum based on centripetal(or was it centrifaugal?) force.
4.At the proper interval, she detaches her blades and it should propel her forward.
What i'm thinking is that it would work theoretically, but only very slightly possible.
Also, might post later if there are no more replies.
