Getting a bit serious, I feel!! Good for them (and Flybe, of whom I am not a great admirer!). Age, ability and experience certainly count, but not always in that order!
Many previous posts refer to young military pilots, not the same, I know. However, they did (and still do) remarkably well !
I had my full "Wings" some time before I passed my driving test! Still alive after a life in aviation ( military and civil) and have full confidence in the younger generation!!
Admire them.
