Just a question, not an assertion at anything. I wonder what the flight currency was of the owner, both a/c & sim. I've flown for major EU airlines where the CP was so busy he didn't fly and even lost his LPC. He then renewed it and went to Seattle to collect the 1st of a new variant and ferry it back. In other airlines the office jocks would do a short out/back once a month to keep current and be in the office mid-morning. It would not be the the first time a prestigious charter popped up and someone hi-up pulled rank to operate it. If everything goes fine it's fine; if the a/c starts to play up technically, or if mother nature + ATC throws a spanner in the works, lack of familiarity can be a factor in decision making, or lack of.
Just a question to those who know.
