Hehehe, you thought C47s were slow? The Ju52's top speed is around 150mph. It's not a good airplane in and of itself. Rather, I think it was a historic innovation when it came out, and instead of keeping with the innovation-making, they just kept marvelling at their (now outdated) wonderplane.
Ah well, I wouldn't mind seeing it in AH, but I bet for flight time I'd still take the C-47 9 times out of 10.
