You are in a long tunnel in a spaceship. There is no gravity. The diameter of the tunnel is about 16 feet. You are in the center of the tunnel, and are not presently moving. There's an unfriendly alien at the end of the tunnel, 500 feet away, that is closing in on your position. Fortunatly, there is an escape vessel docked at the other end of the tunnel about 40 feet away from your position. Unfortunatly, you cannot reach the ladder on the walls of the tunnel. You have no rocket propulsion device on you, nor any sort of weapon. How do you get out?
