Also, what a lot of posters are forgetting is that software is involved in "real" engineering. The work BP is doing isn't happening by the seat of their pants; real numbers are being crunched, supplies are moving along the chain and simulations are running. It's not happening with slide rules and ledgers either: there are software applications enabling all this work they're doing.

A significant portion of physical engineering these days is delegated to software and it needs to engineered properly just like the rest of the system. If the software controlling a chlorine extraction process fails and vents toxic gas, the result is every bit as tragic as if a mechanical engineer had specified the wrong pipe material and that was the fault that released the gas.
