I have been doing a great deal of reading lately and came across some information that I researched years ago. It is on the Soviet Space Shuttle.
Buran-Energia is the Soviet Space Shuttle system made up of the space orbiter called Buran (Snowstorm/Blizzard) and its ultra powerful heavy lift booster system known as Energia and was very similar to our shuttle.
Watch the video below. It is very educational. I will post more on this subject as times goes on.
"When people have asked if I'd like to go in the Shuttle, I said you don't get to fly it, except for landing, which I'd love to do. I wouldn't go unless I could command it." - Wally Schirra
