I was just reading about the first transatlantic flights on wiki
Alcock and Brown are credited with the first non-stop transatlantic flight in 1919, when they flew from Newfoundland to Ireland. I think I’d be right in saying that this achievement has long been in the shadow of Lindberg’s 1927 flight. I always thought that one reason for this could be that A&B flew from an island to an island, and some would think this somehow not the complete thing i.e. not from America mainland to Europe mainland.
But I noticed that Lindberg didn’t do this either. He took off from Long Island. This didn’t make the journey any easier of course, but still it’s not quite mainland America.
So would this make the crossing by Dieudonne Costes and Joseph le Brix in 1927 from Senegal to Brazil the first “true” non-stop fixed wing mainland-mainland crossing of the Atlantic??
