started transatlantic flights during WW2, in August 1940. The aircraft were Empire flying boats fitted with extra fuel tanks. Their names were Clare and Clyde.
They were later replaced in 1941 with regular passenger flights with three Boeing 314 flying boats.
A series of flights continued throughout the war where British pilots were flown passenger from GB
and returned bringing back warplanes from the US and Canada. They even flew in formation at times.
I can't find any record of Air India doing such things, but will agree that they were around in the early 60s when I was crew. Before then BA
used a whole range of transatlantic aircraft including the DC7C and Boeing Stratocruisers.
Not forgetting that later, BA
was the first airline to fly a commercial passenger jet across the Atlantic.
There again BA
was the pioneer of most international routes, worldwide!
