Don't fly on the 'A' of any aircraft!!!
Sunfish, I logged well over 4000 hours in 8 years on the venerable Lockheed C130A model and they were brought into RAAF service in 1958. One of them is still flying (former A97-212) in the USA, still with the Aeroproducts 3 blade propellers. Some aircraft 'A' models last.
