This particular Heinkel 111 (CASA 2111) had an interesting history. According to one source on the 'net it says:
The sole remaining He 111 in regular use is owned by the Arizona wing of the Commemorative Air Force in the USA. It is a Spanish-built CASA 2.111D that was used to transport VIPs during the Franco regime.
It is pretty astonishing that this is the only flying He 111 if one bears in mind that over 7300 were built
I just had another thought: This Heinkel 111 (Casa 2111) is well over 12,500 lbs so one needs a type-rating to fly it in the US. Pretty cool I think to have He 111 or CASA 2111 on your license ...
