@Erdayastronaut Why use Orion atp? Throw out SLS and use a modified dragon. They are already developing a service module for dragon to de-orbit the ISS.
@sscmark One of the tricks for the i3 is that the doors are the B pillars in a sense. The Ferrari is much longer, but with modern day materials there would be no problem making the chassis stiff enough to have the B pillars be part of the doors.
