So I'm watching that link that Gomer posted for the live feed of the oil well. They get the pipe cut off. Now they are just showing the cap hanging in the water. PUT THE DAMNED THING ON ALREADY!!!!

But really, they were so concerned with gettting a clean cut so they could put a seal on that is like a hose washer. That is why they didn't use the shears to do it. The saw got stuck, so they ended up using the shears anyway. Why didn't they cut it higher and put a tapered seal that went over the outside? The cut wouldn't have mattered then.
