Uuups :blush: ...I should have Read The Fine ManualHaha, the MFD's disappearing is not a bug, it's a feature! It happens when you're out of radio contact (no surface base above the horizon), simulating the very restrictive communication conditions in the early 60s spaceflight.
No, please don't roll! That's not what I've tried to say
I just thought that the booster has to be placed ("rolled") 180° on the launch pad.
The pitch program would possibly be "negated" (so 40° pitch-up becomes 40° pitch-down or vice-versa), but no roll program!
But as I said, I don't have any evidence that head-down really was the case and as long as there is no evidence against your current implementation, that's fine :thumbup:
Thanks again for your effort.

The only reference I could find so far about the X- Y- and Z-axis orientation is in this PDF 19680025550.pdf page 33 (Page 17).
So from that drawing a positive pitch would place the astronaut head-down...
But the booster guidance might have a different coordinate system, so not 100% sure...
(On Apollo-Saturn the command module and the booster actually had 180 degree opposite Y axis orientations, for reasons I don’t actually know.)
I hope someone else can find a definitive answer to that anyway.

Just tested 2.1, after BECO an additional booster mesh is still attached to the spacecraft even though the separated booster is still venting behind.
Doesn't that depend on whether you look sideways to the right or to the left?There are photo sequences of the ascent taken from the capsule: https://tothemoon.ser.asu.edu/gallery/Mercury/4/Maurer 220G 70 mm
The camera is pointing sideways, but you can see that the orientation is heads up.
