I lived in co-op housing during college, which was (loosely) administered by the university and separated into different buildings by gender. One year my hall started a rapidly-escalating prank war with a women’s hall when some guys testing a water balloon launcher accidentally put a balloon through their back window from like 100 yards away. Things culminated in a massive water balloon fight on the campus quad that both sides referred to as the “Bitches and Bastards Brawl.”
The past truly is another country.
The reverse. OceanGate saw how planes were being built and said, “let’s do that for submersibles!” even though in airplanes, composites are subjected to <1 atmosphere of tension loading and <2g aerodynamic loading, whereas their submersible was going to be subjected to >400 atmospheres of compression loading, and a much more corrosive environment.
Composites in aircraft have a fairly long and uncontroversial history, and there’s nothing inherently wrong with them in that application. The biggest problem with composites is what happens with them at the end of their service life. Finding ways to recycle them without compromising safety is a good thing, and if it weren’t for Boeing having such a damaged reputation at the moment I think nobody would bat an eye.
