Forgot how in SC3, but I know that David413 in the last shuttle fleet version incorporated some elements of activation with keyboard (like Shift-F8 etc.), to initiate IUS-ASE to set to pre-deployment attitude, and PAM-D separation procedures as well, without focus on vessels (only PAM-D "clamshells" had to be opened with focus on them).
I remember now, so it's based on david413 work ?
I still sometimes use orbiter 2006 for STSP Part two ( for what could of been )!
Thanks
