It was generally held up to now that the ratio thrust/take-off weights should be approximately two. [Gröttrup] discovered … that values as low as 1.2 for this ratio could give optimum results under certain conditions.Remark: The designations R-12 und R-14 are related to the internal project names (also known as G-2 und G-4), not to the rockets installed during the Cuban Missile Crisis

[…] The formal end of the space race occurred with the 1975 joint Apollo-Soyuz mission, in which U.S. and Soviet spacecraft docked, or joined, in orbit while their crews visited one another's craft and performed joint scientific experiments.
A Soviet youth magazine in 1951 is often credited with sparking public interest in space travel. Quickly picked up by US magazines, the idea of extending the Cold War playing board to outer space soon energized the imaginations of politicians, military leaders, and the private sector.
Finally, in a field where the United States and the Soviet Union have a special capacity—in the field of space—there is room for new cooperation, for further joint efforts in the regulation and exploration of space. I include among these possibilities a joint expedition to the moon. Space offers no problems of sovereignty; by resolution of this Assembly, the members of the United Nations have foresworn any claim to territorial rights in outer space or on celestial bodies, and declared that international law and the United Nations Charter will apply. Why, therefore, should man's first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction, and expenditure? Surely we should explore whether the scientists and astronauts of our two countries—indeed of all the world—cannot work together in the conquest of space, sending someday in this decade to the moon not the representatives of a single nation, but the representatives of all of our countries.

When the valve opened at a height of 168 kilometers, the gradual but steady loss of pressure was fatal to the crew within about 30 seconds.
