In June of 1919, two daring British aviators made the world's first successful non-stop flight across the Atlantic Ocean from North America to Europe using a modified Vickers Vimey airplane. In just 16 hours, they achieved what up until that point, required days to accomplish by ocean liner. John Alcock and Arthur Brown’s transatlantic flight was celebrated around the world as a monumental achievement, but regular passenger carrying flights were still decades from becoming reality.
