This Portuguese Hercules still carries its markings to celebrate 80.000 flying hours on the tail and 42 years Bisons squadron markings on the fuselage. These markings were applied in 2019. I first saw this same aircraft back in 1983, then still as the short C-130H version and in a brown/green camouflage scheme. Amazing, more than 40 years ago! Old aircraft, old spotter...
