The Super Connie made 2 or 3 visits to GVA
this summer. I'd love to see the Red Bull DC-6B but haven't made the trip to Salzburg yet (I live near GVA
). That must be the most perfectly preserved propliner of all. Looks better than new in photos. It has the advantage of having a full original passenger interior while the Swiss Super Connie was originally a US Navy troop transport so has a rather basic interior with some non-original seats installed.
I was lucky enough to fly on a few Super Connies and DC-6Bs when they were in their latter few years of airline service.
