I worked as a NDT tech about 2 decades ago. Got trained at Hellier college in RT, UT, PT, MT, and ET. Most of my summers were spent going to ski areas and testing the grips that hold the chairs onto the cables but I also did inspect valves for nuclear plants and ships (at a local factory). At one point I was almost recruited to go to China. They were building power plants at record speed and were paying insane money to get anyone they could to go. But it was in the middle of nowhere and foreigners aren't allowed to drive. So either you were working or you were hanging out at the hotel with the other techs. Returning home for vacation was a major process so it was discouraged. You could request a driver to take you around but even going to a major city was an overnight event. If it wasn't for all the driving I probably would stuck with it.
