And for a while, I thought that the new update had killed space travel.

I proved myself wrong.

I was going to complete the concept as a standard project, but then I saw Flyingthing's SSTO challenge. Quite a coincidence indeed. This thing has a ton of thought put into it, and its function was extremely hard to get, as gun physics is extremely weird at high altitudes/speeds; it is probably my most technologically advanced build to date. The SSTO uses gun-based propulsion to function fully in a vacuum. No mods needed. For the most part, the type of propulsion used is obsolete with the new update, but I discovered that it still works on 2D VTOLS (that being, VTOL aircraft that are locked into an upright position by a gyro). The above aircraft is the result of that discovery, and it fits within the requirements of the challenge.
