It could certainly come back - and to be honest, it would be more useful in America than I have found it to be in Europe. When I lived in the United States, I got used to using an airplane for transport. There are airports everywhere, they have IFR approaches, FBOs, 24 hour opening, courtesy cars, no landing fees, etc. etc. I know not everything's perfect in the US, but it is by far the best place in the world to fly (and I've kept a share in a Super Decathlon in Maine so that I can come back and enjoy it regularly!).
Here it's very different. If I want to use my airplane to fly from home in France to work in London, I need to make a stop to clear French customs - and I need to notify customs at between 4 and 24 hours in advance at most airports - and when I get to London there are almost no airports with approaches that accept GA. The few that do are ridiculously expensive to use, and almost all GA airports shut at sunset. It is much easier to use the airlines, and with fuel at ~$9/usg it's much cheaper too. So I am not flying the Mooney enough to justify owning it. I'm thinking of perhaps going back to flying something small, slow and fun - just for the pleasure of being in the air. And maybe something with skis on it so that I can get back into landing on the glaciers in the French Alps, which is almost the most fun that you can have with your clothes on!
I advertised the Mooney yesterday. There has been a lot of interest and someone's coming to view it tomorrow. It is not the cheapest, but I think it is one of the nicest! I need to take some interior shots - I've had to settle for showing the seats outside just after they were upholstered. I don't want to hijack a thread about Bob's lovely airplane, but if anyone wants one that could be made almost as nice as his, here's the advertisement: https://www.planecheck.com?ent=da&id=48000
