About a year before I went to work there, a local refinery had an incident when they were moving a large Lampson crane and did not do a ground compaction survey, and it gave out.
The crane went over and was cut up into scrap metal.
The stick barely missed an office trainer owned by union pacific resources and the guy sitting in the office, and fell across the Anaheim street bridge in Wilmington.
the crane was a sister to the one pictured below:
