Thunor, my comments were not intended to be toxic, but plain truthful. In my retired state, I could not now visit the very flight decks I worked in for 34 years myself. The shutters have come down. The reasons are valid- Mukonyi and the Fedex DC10 incident- and that was a fellow deadheading crewmember! I think there would be very limited value for what you want in a single observing flight in a strange aeroplane if you could get it. How about other solutions- investing in a short simulator course?
