military or seconded from a major airline like BA then I see no issue. Their training and fitness would be beyond question.
BuzzB - you really are clueless!
Plenty of military pilots cannot pass an EASA Class 1 Medical, as they test different parameters. As for fitness - an ex RAF, now civvy mate of mine recently posted on his FB page that he had just run for the first time in his life more than 6km!
Military/Long-haul/bizjet pilots are all different sorts of flying. The best pilots for flying biz jets are biz-jet pilots.
