Michel, thank you for the illustrations. Very interesting.
They really illustrate the astronaut accommodation problems faced by the Grumman engineers on the Apollo LM. How to accommodate the pilots so that they have visibility for launch/docking (forward visibility), and landing (rearward/downward visibility), but since ROMBUS would launch from Earth the G-forces on the pilots also have to be accounted for. According to the illustrations, the pilots would be crushed down into their seats, versus pushed into the back of their seats (as on Apollo / Shuttle). Seated as they are in the illustrations, it looks like they would actually have little forward/downward visibility, only lateral.
For a pilot, vertically landing something as large as ROMBUS (not to mention finding a suitable landing spot) would have been quite "exciting" I would think.
