Amazing, Don. Simply amazing.
Now - I'm looking at a poster I've got and it appears that the launch tubes may actually be on a level above the landing bay. Which would mean that, along the inside wall, perhaps at the front end, are elevators that "load" the viper into its launch tube.
And I doubt any kind of catapult system could use a curved launch path with any degree of efficiency. Some of the energy would have to be used to direct the viper along the curve, rather than just pushing it out at maximum thrust.
