I found this while looking for pics of the above:
"The aircraft (which has a profile similar to a Boeing 747) that transports Goldfinger and his car out of England is actually an Aviation Traders ATL-98 Carvair. This was a heavily modified Douglas DC-4. The 747 didn't make its first flight until 1969 but the Carvair entered service in 1962 (two years before Goldfinger). The flight number for the flight in the movie was British United Air Ferry Flight VS 400 to Geneva, Switzerland. "
