Truck driving isn't percieved the be a glam job. Airline flying is. But it isn't. T&Cs are now pretty crap for someone who may well have borrowed or begged £120K to get a licence. And there is no guarantee of a job at the end.
I must stress the point, there is no glamour in aviation as there may have been 30 years ago. I would rather my son become a builder with his own small company if I'm honest.
