A Harrier parts pack that provides everything but the landing gear and the hinges for under the wings, to build a Harrier Jump Jet. BREAKING GROUND IS NEEDED FOR THE ROTATING VTOL ENGINES. As I can't build complex internals yet, it uses a slightly modified Harrier IVA from Cold War Aerospace and the license reflects that.
Prebuilt craft within the SPH folder that is in the main folder.

Gear, Toggle wing wheel hinges. 1,Toggle engines on/off. 2,Toggle transition from vertical to forward thrust. 5,Toggle ladders. EVA is right side. 6,Toggle hinge lock for wing wheels. Custom 1, Adjust thrust limit of front engines for a bit more forward thrust, just make sure to revert them to 45 for hovering and landing VTOL. These are cruise engines and have a spool time, so make sure you adjust ahead of time and let them catch up or you will have a very hard landing. Over 2 thirds throttle to take off and then as soon as you do drop it just under 2 thirds and tilt the nose down 5 degrees to get forward momentum before transitioning.
