One of the saddest things, if not the saddest, is it takes away one of the final opportunities that were available for people, mainly children, to come up and see what goes on up the front on the flight deck of an airliner.
How many of us on the forum older than our mid teens were inspired by going up front on an airliner when we were younger? Quite a few I suspect. The charters that will inevitably replace some of our civilian carrying passenger routes will, just like any other civilian airliner, have the door firmly locked.
That's one thing we'll miss.
