I know @IamJudd posted it, I'm pretty sure this is right - I've never seen it, but I remember there was a Mythbusters episode which referenced this scene.
Well done IanW - if you've not seen it, it has everything an 80's movie should have... And it's just had a 4k re-release!
Reminds me of the start of Hacksaw Ridge for some reason. Never saw past the first twenty minutes or so of that though, got bored.
