Skylab and NASA Pioneer In My Family.

Such in life no one does it but you! Anything of value takes effort.
In my family we have a NASA pioneer that worked on cabin pressure for 
APOLLO-1. They had a accident but this was a first of it's kind.
It effected my relative with what happened but he accepted this was a
first of it's kind. There was to many things going on at once with many 
changes. This was never done before and in a mess a mess would happen!

~~~~~Aviation had suggested using an oxygen/nitrogen mixture for Apollo, but NASA overruled this. The pure oxygen design was judged to be safer, less complicated, and lighter in weight. In his monograph Project Apollo: The Tough Decisions, Deputy Administrator Seamans wrote that NASA's worst mistake in engineering judgment was not to run a fire test on the command module before the plugs-out test.

But the point of this story is the point to be a pioneer a first of a kind.
You don't have to go to NASA and do it just find it and do it.
You will have mistakes and so you don't quit you learn from them and go on!
NASA and everyone did not quit just because of the APOLLO-1 accident
and we ended up on the moon!

~~~~~“To me, it's an emotional thing,” said Bill Barry, NASA's chief historian, who was 9 years old when the fire occurred. “Because space is risky and dangerous and it's hard to do and can be expensive. But ultimately, you want to do it in a way that you don't hurt anybody, and everybody comes home alive. This is a reminder that you have to be on your toes, and make sure that happens.”

In the aftermath of Apollo 1, NASA did make space flight safer, and in 1969, Neil Armstrong and Buzz Aldrin walked on the moon with Apollo 11.

“We found the problems,” said Bob Sieck, a former NASA launch director. “We fixed them. And as a result, the first time we attempted to put astronauts on the moon, and get them back safely, we did. And so, from my perspective, I think that the Apollo 1 crew would be good with that.”

~~~~~Skylab was a United States space station launched and operated by NASA, and occupied for about 24 weeks between May 1973 and February 1974 – the only space station the U.S. has operated exclusively. In 1979 it fell back to Earth amid huge worldwide media attention. Skylab included a workshop, a solar observatory, and other systems necessary for crew survival and scientific experiments. It was launched unmanned by a modified Saturn V rocket, with a weight of 170,000 pounds (77,000 kg). Lifting Skylab into low earth orbit was the final mission and launch of a Saturn V rocket (famous for carrying the manned Moon landing missions). Three missions delivered three-astronaut crews in the Apollo command and service module (Apollo CSM), launched by the smaller Saturn IB rocket. For the final two manned missions to Skylab, a backup Apollo CSM/Saturn IB was assembled and made ready in case an in-orbit rescue mission was needed, but this backup vehicle was never flown.

The station was damaged during launch when the micrometeoroid shield tore away from the workshop, taking one of the main solar panel arrays with it and jamming the other main array. This deprived Skylab of most of its electrical power, and also removed protection from intense solar heating, threatening to make it unusable. The first crew was able to save Skylab by deploying a replacement heat shade and freeing the jammed solar panels. This was the first time a repair of this magnitude had been performed in space.

A first time a repair of this magnitude had been performed in space!
