Just a comment that diagram of the Proton variants should be credited to Asif Siddiqi and Peter Gorin. Those drawings were done by the Peter (who tragically passed away) and commissioned for my book Challenge to Apollo: The Soviet Union and the Space Race, 1945-1974 (NASA, 2000). Unfortunately, they were mistakenly put online by NASA without my permission. (Lost cause when things are put online!). Best wishes, Asif
