First DC10 in the BCAL Fleet
I assume, based on the colour scheme, thats actually the DC-10 prototype?
It was N10DC, the DC-10 prototype that was on it's world "Friendship Tour". The aircraft visited London Gatwick Airport in July 1972 and was shown off to prospective customers such as British Caledonian Airways and Laker Airways.
I'm sure that everyone is aware of the excellent BCAL site,
