Maybe this thread is relevant 
(with apologies to the pilots who had to fly these things, by hand, 400ft above the sea, and get a Class 1 medical every 6 months)
I can remember looking up and having it pointed out to me that the planes flying overhead were now Trislanders, with an extra engine… before this particular one was flying, and not long after I was walking!
Wonder what the aircraft’s fate will be? I can’t imagine Trislanders make very good private aircraft (especially if the engines are in need of overhaul).
