I think I saw this a few years ago the one scene I remember is they were testing the tail of a plane after an accident of the same plane type by moving the rudder back and forth repeatedly in a cold environment and they had been doing this for like a month and nothing was showing up  when this guy’s boss calls him and tells him to stop the test and give up and that is when the tail completely snaps. The movie was in English I’m pretty sure. I saw it on YouTube actually but I am pretty sure it originally was a movie it was in black and white or maybe sepia of some kind I can’t remember really
