At T plus 40 seconds Apollo 8 went supersonic and the ride smoothed out. Now it was quite again, but Borman kept a watchful eye on the trajectory readouts. If there was a Saturn malfunction he could whisk the capsule away just by twisting the abort handle. This would trigger the escape rocket.
Until now the astronauts knew, in the back of their minds, there was a possibility that a malfunction would turn this countdown into just another practice run and they would have to get out and try again another day. But, as the count reached T minus 15 minutes, there was no doubt, they were really going.
For now the mighty Saturn V stood empty. But overnight, even while Borman’s crew slept, technicians would ready it for departure. By morning its enormous fuel thanks would be filled with cryogenic propellants, until the rocket would contain the explosive energy of an atomic bomb.
The successful Apollo 7 flight cleared the way for a US moon landing in 1969. Still a lot of flight and ground testing remained and there would probably be surprises. The greatest concern was Nasa had to complete three virtually flawless missions and achieve every major test objective before a lunar landing could be attempted. The odds seemed to be stack against NASA.
Frank Frederick Borman, II was born on March 14, 1928, in Gary, Indiana. He is of German descent, born as the first and only child to parents Edwin and Marjorie Borman. Because he suffered from numerous sinus problems in the cold and damp weather, his father packed up the family and moved to the better climate of Tucson, Arizona, which Borman considers his home town. He started to fly at the age of 15.
Perhaps the most significant point about the lunar-orbit flight proposed for Apollo 8 was that the command and service modules would fly the same route to the moon as would be used for the actual lunar landing.
An ‘A’ type mission would be flown with a Saturn V and be used to test the Launch vehicle, spacecraft, and a high velocity lunar return. Nasa cover the ‘A’ mission with Apollo 4 & 6.
A ‘B’ type mission would be flow with a Saturn IB and test the lunar module development, and propulsion, and launch vehicle staging. This was accomplished with Apollo 5.
A ‘C’ type mission would be flown with a Saturn IB and test the command and service module and evaluate the crew performance in low earth orbit. This was accomplished with Apollo 7…
Trouble began on the sixth day of the flight, November 17. The capsule developed an atmospheric leak, the pressure first dropping from 760 to 380 mm of Mercury. With the drop in cabin pressure all the animal test subjects died. It would have killed any Cosmonaut not wearing a spacesuit.
