Very basic spacecraft.dll implementation of Soyuz 7K-OK male / female docked vessels. Each Soyuz is configured as three docked spacecraft. This way, you can undock and separate the reentry modules. Only the service module has fuel, so you need to select it to manouver.
This a very basic inplementation, using Castor Soyuz meshes (required):http://www.orbithangar.com/searchauth.php?search=castorp
It's intended as a base for further development, and to share with the comunity what I have done so far. It is not intended to be a complete addon.
Do to: launch configuration, reentry module realistic parameters and parachute, other Soyuz versions.
