Personally I would have to say Mechjeb is a spectacular mod, for an autopilot function. The Mod creator gets a gold star from me for effort in building this mod. The newest pre release build is astounding, Jeb can launch, orbit, land, dock, transfer all by itself. It gives data to the user if needed and its accurate to my assumption. Sometimes it does seem to use A LOT more fuel opposed to when I am at the controls. When I fly by WASD there are times I can complete a complete launch,orbit,docking, and landing, some to most times successful. Personally I consider myself a tester of all others creations, the game being in alpha is one of them in constant testing, along with all mods and parts created. This Game KSP is an astounding game Best purchase I have ever made aside from my pc ;D . This is only referring to original post about a MechJeb review nothing else intended by this post at all. I don't bother with belittling people and their opinions that's their opinion they're entitled to it. If anyone wants to voice a complaint about using mechjeb, don't bother I will not respond to it. Have a Great Day creating some spectacular bases, Stations on those far away rocks or gas giants. Also remember .....crap just crashed into my solar panels....sike hah
