B9 makes career mode like a whole new game. This plane can land anywhere, barely needs any room to take off, and has a fully functional science lab (I haven't even unlocked supersonic flight yet!) It's a blast to fly, too. You can get anywhere on kerbin with one tank of gas, and then some. If you retract the front landing gear, Jeb doesn't even need a ladder. You can also repack the chutes from EVA by walking along the aircraft's spine. Craft file Mods: This plane only uses b9 and stock parts so far. I will definitely upgrade the design and add space capabilities as more technologies are unlocked
