Perhaps if we are going to investigate the Captain's 'Flight Sim' activities, we should investigate all aircrew who take photographs of aircraft, or give up their own time to fly/commentate at air shows, or do other aviation related things.
While we're at it it, why not investigate all the ATCOs who volunteer to work at RIAT every year? Doing aviation related stuff in your own time?…Must be suspicious.
For many professional aviation licence holders, (myself included), aviation is a passion, not just a job. For others, (quite understandably), it is something which is left behind at the airport/ATC Centre, (or wherever), when heading home.
