Interesting tidbit of history. It's one of those things I have never personally considered.

Another of the rabbit hole vids.
I grew up with metallurgists, physics PhD's and EE's. Some of the first ultrasonic test equipment was developed in my living room as I was a kid. I knew Snell's Law at age twelve, tutored by those folks. They worked for a steel company producing nuclear grade tubing for Groton Connecticut shipyards... Long gone now, Babcock & Wilcox. They produced tubing for nuke subs, they were originally a boiler making outfit. Later, in the late '70's, I ran ultrasonic test equipment they'd developed in my childhood home. Seamless stainless tubing. Crude by today's standards, search heads of Lucite, "Hamiclear" as the interface and Sperry oscilloscopes to "see" imperfections. Amazing to see how ultrasonic uses have has developed.

A funny aside to that company is they couldn't find a reliable source for the insulating materials used in the furnaces, so they bought an outfit named Insul-Brick. Turned out the biggest customers for that product were mink farms. The critters needed something to chew on to keep their teeth short and sharp...
