Orbital Mods. Addons for Orbiter Space Flight Simulator

Fixed the Soyuz I addon and resumed working in the alternate versions I was developing at the time. I'm focusing in adding a working control panel and animated parachute deployment right now, resuming work from where I left it. Unfortunately, I was working on both things in parallel so I've got two different sources to work upon and it's a real pain to figure out what changes were done to the 'stable' (*cough*) Soyuz source in each case.

Added: Apollo-Soyuz ASTP.
Added: R7 8K78 Molniya.
Added: R7 Progress.
Added: R7 Soyuz ST.
