Another thing I don't get is the placement of the nacelle pylons. They sit too low and too far back on the secondary hull, go straight into that cavernous shuttle bay, and yet there is no place for the intermix chambers to be positioned from engineering. Doesn't make any sense.
Still don't know why they didn't keep the articulated clam-shell shuttle bay doors. It looks far too easy to hit those slanted things with a shuttle on the new one like Xavier_Storma
