Hi all,

In this weekend I've had some moments to launch my own Apollo 7.

Everything is working fine following, I've only a little question.

During the launch the S-IVB Cut Off at (if I remeber well) +08:35. In the Apollo Reference Source Book the S-IVB cutoff  is at +10:14.

Why this difference ?

Hello,

It may be the simple solution, that Apollo 7 rode on a Saturn IB (I remember too the cutoff at T+8:00). The T+11:00 minutes mark for MECO was on the Saturn V flights.

Maybe there is another solution, I don't know of. But maybe one of the professionals could confirm or decline my idea.

Cheers,

I never checked that, but I suppose because of wrong Saturn 1B performance. We aim for the correct orbit and not for correct burn time, only the Apollo 11 launch is optimized to work "by the historic numbers".
