Yep; I know of several. (Don't believe the "you are too old cobblers!!" It's utter rubbish.)
One example joined Air Southwest with age circa 50 years and did rather well ie P1 / Trainer etc.. deservedly so.
Another mate flys the Phenom 100 - he was 47 prior to his career change.
These two examples are the tip of the ice berg.. grey cockpits are the way ahead.
