I wonder what the flight path would have to look like - I assume you wouldn't be able to accelerate in a circle on the ground and then tilt upwards because of the G force of the tilt. So you would either sling horizontally at a fairly slight incline (taking advantage of the curvature of the earth, but imagine keeping that flight path clear), have a slowly increasing ramp that would probably have to be really long to manage the G force, or accelerate in a vertically-oriented loop (which would have to be huge to cope with faster speeds). I'm guessing the slow ramp is most practical. Either way, there's some interesting info on the concept at https://en.wikipedia.org/wiki/Space_gun https://en.wikipedia.org/wiki/Space_gun and https://en.wikipedia.org/wiki/Mass_driver https://en.wikipedia.org/wiki/Mass_driver.
