took a look and noticed 3 things: 1 (and the reason you cant move) is because you left Red 1 docked to the Zeus. You either have to undock the viper and slide it back in the tube manually (or write down the co-ordinates the fighter is at while docked, and then set it back to those same co-ordinates after you undock it).
second thing is initial speeds: The Zeus has an initial speed, so it is going to move at the start of the mission and you will fly through the walls on the way out. ships-initial status - velocity, set to 0. This also persists for the player's viper and has to be changed or you'll just start flying down the tube without any keypress.
and the final thing, repeat count for the event 'Launch' has to be very high. 999999 or some random big number. also: the interval time for this event has to be set to 0 or you'll stutter down the tube rather than accelerate.
Hope that helps.
