I think the first mention of cause here came from ribbing our deceased and distinguished St. Petersburg member who shot back something like "At least we didn't put rubber gaskets on our rockets."

Challenger was an operations management failure, yes, and, yes, the limitations of the system were known, yet disregarded. Cause was the O-ring and colder than usual temperature at liftoff. Yes, and unwarranted haste.

Though one thing I did learn from a long career in engineering is that we! That is meaning the world in general, only seem to move forwards with our technology when built on the ashes of disasters be them large or small.


The only lessons in my life I truly did learn from where the ones I paid for!

damascus, I was discussing with another member today the importance of the proper use of words and vocabulary, in this case with the US space program. In part:

"I was with the Mercury and Apollo astronauts and had an edge because the head of MSC was Bob Gilruth who hired 25 of our top engineers when our 105 Arrow was scrubbed because US wouldn’t buy it. Bob, who was also interested in our fixed-reef hydrofoil program, had a gleaming white Arrow model on his desk. He said it was the best fighter ever built (it was at the time). Two top guns were Canadians: Jim Chamberlain and Owen Maynard. Owen and I were relaxing after dinner at his home when the phone rang: Grissom, Chaffee and White burned to death in the command module at the Cape.

"Interesting point for the world in these parlous times was how Owen got to the top. Words mean something. When I asked him how he got to running things, he said it wasn’t because of his engineering skills. NASA had him investigating rocket failures—I think Titans—and he was so good at spreading blame among manufacturers that NASA pushed him up. Owen was in charge of engineering Saturn/moon command module, Jim built Gemini program. All this came handy when Apollo 7 or 8 started tumbling over Japan, I was called in to report live to Canada, and acccurately speculated cause was a stuck small thruster."

We learn from mistakes, certainly, but things run more smoothly in all human activity with proper use of language, communications and cooperation.

Gemini 8 was the thruster incident.

Apollo 1 was an engineering and manufacturing disaster.

It was caused by..... (drum roll)..... unwarranted haste.

Deadlines. Pressure. Economics.

Most agree after the fact that the Apollo 1 accident was not only inevitable, it was necessary and required for the ultimate success of the program and achievement of it's goal.

The saddest fact is that lessons are frequently temporary, and we have to relearn them.
