ok, here's the problem. I've got a pan stuck (horizontally) flat inside a pressure cooker and I just can't get it out. The outer circumference of the pan is exactly the same at the inner circumference of the pressure cooker and I have things under this pan which I was heating in the pressure cooker. The pan is just about 1mm thick but it's real tough and can't even bend. Here's 2 pics, one showing the pan stuck in the pressure and the other showing a similar pan. I've tried to pluck out, hammer out, etc., the pan but it only made things worse.
