Weakest link
This story about how weak rivets could have doomed the fated Titanic (via Abi) proves yet again that connections are often the weakest links in structural integrity.
My educated guess on Titanic’s failure until now had been hinging on uneven material microstructure (or molecular level grain distribution) at subzero temperature in steel—as the primary cause. In this of course, I assumed that connections were taken care of. It appears they weren’t.
