Dependency Warning! This shareable requires that you have the Interstellar and B9 Aerospace mods! If you don't have these, you can find the latest versions here: B9 Repack for .23.5, Interstellar
These are basic aircraft/spacecraft designed to be used for a variety of purposes. I'll eventually upload the earlier prototypes, but the Mk. III will by my very first submission. It's fantastic fun for atmospheric flight, but also has a docking port on the bottom in case you want to strap some rockets on it and put it in space for refueling and what not.
I've also set some action groups to make flight more fun/interesting
1: Opens 2 small air brakes
2: opens all air brakes
3: Cockpit lights on
4: Retract Cockpit
As a note with the Mk. III, I designed it to only have to land on a runway in an emergency, and to mostly operate in conjunction with space stations, so if you go to land and your undercarriage air brakes are open, they will break off! This doesn't damage the integrity of the aircraft effect it's performance.
You can drop it in both your SPH and VAB files depending on if you want to take it for a jaunty flight as is, or build a rocket around it/put it into orbit.
