Just to throw something else in regarding engineering.
Once upon a time in the Middle East, a 212 would go in for a 100 hour service. The civilian company, (with initials similar to Wastelands now!), would take about a week for the job to be done.
On the North Sea a 212 would be taken in for the same routine and
with 2 engineers would be back on the line the following morning! If it wasn't, the 'interview without coffee' was the next step. No aircraft to fly, no revenue, ergo no pay, a great incentive to work hard whilst on shift!!
