The 60 minutes story sounds so much like my experiences working for a contractor for an oil company in the oilpatch. (admittedly on solid ground and only for a few years)What I mean is they follow the safety rules and procedures just fine when things are going well and on budget.
However once they start to have trouble through mistakes, unanticipated difficulties, or just plain bad luck then they start to ask you to take short cuts.
Stuff that normally needed to be x-rayed or hydro-tested (according to company rules and the law) was to be bolted right into production.
They were already way over budget on this well having to abandon and re-drill it. I'm sure the BP guy who was ordering them to take a shortcut was receiving enormous pressure from the higher ups at BP.
