The sad truth is that if you’ve been flying for the last thirty years and are made redundant in your fifties, then your future career options are very limited. By the time normality returns you will be too old to justify the expense of retraining for a few years before retirement and too old to start over in another field.
Aviation skills are highly specialised and whilst some such as leading a team are useful, you are usually either over or under qualified when applying for a new job. Driving seems to be an area that unemployed pilots have moved into, everything from combine harvesters to busses to dump trucks and delivery work.
Under thirty, you can retrain, around forty and you’ll be picked up again when things improve. Cross the half century and it’s difficult, over sixty and it’s retirement.
