If Nasa where to sink a large tube down a few miles into one of the deepest parts of the ocean or a spiral tube not so deep. Then fit electromagnetic monorail running gear to a sledge and then put a space cargo vehicle inside the sledge. With ball valves to compartmentalise the tube off to keep a constant pressure with inert gases as the space shuttle accelerates using electromagnetism to gain altitude and then loses the sledge. Next fires it's main rocket engines to carry on up to space. Would this idea work and would it save money on fuel if the space cargo vehicles where only say 5 ton cargo holds. Also they could be reusable with their rocket engines.
