Apologies for being so broad in the title but this will consist of a couple of questions in one.
As I'm sure most of use are aware modern commercial aircraft being manufactured no longer incorporate a flight engineer, this role - as far as I know - has been taken over by onboard systems monitored by the pilots.
Obviously there are a number of airlines out there flying older aircraft that do require a flight engineer, which airlines still actively hire F/E's? Do airlines still train people for this position or purely rely on hiring people already trained? I'm thinking more along the thought process here of 'When the older F/E's retire, how are they replaced?'
Finally, what happened to the F/E's when this job was phased out? Were they retrained as pilots? Merged into an office job? Flat out dropped from the company?
