Good thing you weren't standing there when it fell.That thing would have left a mark it if had landed on you!
I saw about 20 or so cylinders of various sizes leave where I work in the scrap box not to long ago.All because we got rid of some equipment and these were spares.Brand new.Scrapped.As I stood there looking at all the differant lengths and diameter cylinders, I thought of all the lifts and splitters I could build, maybe even a knuckleboom or something.I did manage to get a couple of the smaller ones, but them larger ones are too much weight for the helicopter ride.
