It's not as simple as " the pilot and the engineer didn't do their job".
That's an outdated way of viewing incidents and accidents.
Put it this way, if you are a passenger on an aircraft, would you rather the Engineer dealing with your aircraft had three aircraft to dispatch in the next 90 minutes or just the one? Which Engineer would be more likely to miss something?
I think working hard is something to be proud of and I don't mind getting my hands dirty, I'm not a "Union guy" either, but there comes a time when the resources allocated to the job are insufficient to maintain the acceptable level of safety that Joe Public expects. It's great to have a £30 airfare, but it's better to have a £35 airfare and frontline operational staff that aren't pressed for time even when things are running to schedule.
