This is the 20-passenger version of my trans-system VTOL shuttle, landed on the Mun after a vertical descent wheels-down landing. This craft makes use of the PanzerDrive Exotic Energy mod and the PanzerDrive Exotic Engines mod which add the ZPM nodes you see along the top center of the fuselage and the Graviton Thrusters you see on the underside of the fuselage and on the rear nacelles mounted to the cargo ramp module in the rear. I revised this design to a 36-Kerbal shuttle by adding a second 16-passenger crew cabin immediately in front of the cargo ramp because Kerbals were falling out of the cargo ramp area during egress and dying before being able to get into an orbital configuration for EVA transfer to the front crew cabin.
