Maybe Webb Hubbell went where “no man has gone before”. Or since.

Yep, but a specially formulated version is required for the temperature extremes and vacuum of space. Since that document indicates that NASA already knows this, we can assume they used the stuff. The conclusion might be that something else caused the problem.

The opportunities for failures are mind boggling. As much as we'd hate to think that those guys simply didn't use thread locker, that is still within the reach of reality. It would never have survived launch. Think of how much that failure would be worth.

The incident does call for an investigation. Negligent parties need to get their resumes ready.

I like the way safety wire looks when installed correctly.

I monitored the demolition of a fairly new building in Seattle. 14 stories, about 8 years old. Somebody forgot to put a dab of epoxy on the end of the rebar. Water got in and corroded them. They spent years and millions trying to repair it, then ended up tearing the whole place down.

What a great audio - funny. I have no idea on the worker(s) getting fired or whatever. And my client said “And not just the worker, but his boss, the company inspector, the city inspector - they all dropped the ball.”

I mentioned to one of the young construction workers on what a waste it all was.

“Whatja mean? It’s work for me - and then I’ll get to work building the new one - that’s not a waste.” I didn’t bother trying to explain myself.

Oh - the kicker. It was built and owned by the local Construction Union so as to provide income (apartments above and retail on the ground level) for their pension fund!

LGBTQ Advocates Try to Halt Mississippi ‘Religious Freedom’ Law The Mississippi law was supported by Baptist and Pentecostal groups, and the Washington-based Family Research Council gave Bryant an award for signing it. Opponents protested outside the Governor’s Mansion in Jackson and executives of several large companies, including Coca-Cola Co. and Northrop Grumman Corp., called the law as discriminatory and said legislators should repeal it. - https://www.nbcnews.com/feature/nbc-out/lgbtq-advocates-try-halt-mississippi-religious-freedom-law-n697076

There's always the case of NOAA N-PRIME...

On Saturday, September 6, 2003 during an operation at Lockheed Martin Space Systems Company (LMSSC) Sunnyvale that required repositioning the Television Infrared Observational Satellites (TIROS) National Oceanic and Atmospheric Administration (NOAA) N-Prime satellite from a vertical to a horizontal position, the satellite slipped from the Turn-Over Cart (TOC) and fell to the floor (see Figure 3-1). The satellite sustained heavy damage (see Figure 3-2), although no injuries to personnel occurred. The exact extent of the hardware damage is still being assessed.

The operation scheduled for that day was to shim the Microwave Humidity Sounder (MHS) instrument by removing and replacing the instrument. This operation required the spacecraft to be rotated and tilted to the horizontal position using the TOC. The spacecraft fell to the floor as it reached 13 degrees of tilt while being rotated. The reason was clear from inspection of the hardware: the satellite fell because the TOC adapter plate was not secured to the TOC with the required 24 bolts (see Figure 3-3).

Turns out somebody needed some bolts, took them off the satellite that was just sitting there and forgot to tell anybody. Cost to fix the damage was in the neighborhood of $135 million.
