Comment Re:Why (Score 1) 117

And yet all the cool kids love Python and YAML these days, both of which break in fun and interesting ways if you get the indenting wrong.

But that's by design, and is very clearly spelled out. And if you can't deal with Python's formatting rules, maybe you should go back to BASIC. The rest of us are making great stuff with it.

Comment One Feared The Seal Design & Did NOT Quote! (Score 1) 93

At the start of the Shuttle design, RFQs went out to thousands of suppliers in the aerospace sector including a friend & mentor of mine.

Rudolph Kreuger, was an expert is seal design of many types amongst his aerospace contributions. He was a professional engineer and took the proposed rocket stage seal design specifics for the contract seriously and did his calculations.

His conclusion left him concerned about the viability of such a proposed set of conditions for the seal through the range of use conditions so he declined to quote.

The interesting thing to me was that for such a SUPER critical seal, I would have expected that an engineering company would want to find out why a recognized professional engineer sought to not quote the design to learn what they could for future design work.

Doing a critical point analysis ought to be part of every significant highly stressed assembly & I wonder if it was finally done correctly. It seems to have been ignored if it was.

Rudy, died over a quarter century ago, and as far as I know, no one but me and maybe his sons ever knew about this proposed design as he was a very quiet person. Putting yourself into public view can have all sorts of unintended consequences, which I surmise Rudy wanted to avoid.

Comment Re:CFC-free foam caused it (Score 1) 93

It was said at the time that the white paint on the early shuttle tanks served to also keep the foam together and reduce drag on it.

They scrapped it to save money and increase payload by a tiny fraction. But mostly to save money.

Engineers: this is necessary.
NASA Bean Counters: nah.

Every freakin' time.
