in 1981, 114 people were killed in a walkway collapse at a hyatt regency and it was easily preventable

TLDR: site proposed a change, engineer did not realize it doubled the load on the hardware and approved it

one of the things you do in school for mechanical engineering is read examples of ways things can fail and the consequences of it

this example always stuck out to me because the change seemed innocuous and when you’re in a rush, you’re constantly finding ways to reduce clerical burden to keep projects moving

this story taught that the clerical work matters. do the boring work and prove yourself right, always

it also shows the clerical work can and should drive new calculations from first principles. even if the engineer had relied on the previous calcs, they would have gotten it wrong because the FBD changed

i could see seasoned engineers making the mistake in thinking that you would be wasting time re-deriving the calculations, and they would be wrong

takeaways: don’t just recheck your work, re-derive and prove the work. there is no rushing when safety is involved

grok this post for more information on what happened

Can you top this soldering mistake?

In 1980 in Russia, at some subcontractor facility, someone used leaded solder instead of lead-free solder in a fuel filter that was later fitted to a Vostok 2M rocket at the Plesetsk launch pad.
No problem, it's soldered correctly, so they thought.

Only problem is that the Vostok 2M used high test peroxide (HTP) to power the turbopumps, and lead is catalytically active and decomposes hydrogen peroxide on contact. This leads to rapid exothermic decomposition, fire, and ultimately a big 400T of TNT KA-BOOM.

48 people in the ground crew died due to someone at a subcontractor using the wrong type of solder.
That was a very bad day.
They didn't figure out the issue until a year later.

Think twice when you next select your solder type.
