Had a fly once fry to the back element of a projection lens at a theatre where I was a projectionist. What a great job it was. Carbon arc lamp houses, big Bauer 70mm projectors that I was trained to run and repair, grounding myself while rewinding the big heavy reels of film so the static charge wouldn't blow me across the room. The salad days. We never knew how good we had it. Now some mouth breather "manager" pushes a button and goes back to his spreadsheet. Very sad.
