Step 1 : Introduction to the question "Where did the first nonstop transatlantic flight depart from?"
...In June of 1919, British aviators John Alcock and Arthur Brown made the first nonstop transatlantic flight from Newfoundland to Ireland. Back then, there were no airports, just a field from which the Vickers Vimy (their airplane) took off. Theirs was the first nonstop transatlantic flight, but not the first transatlantic flight: A U.S. Navy seaplane had flown from Newfoundland to Portugal in May of that year, with a 10-day stop in the Azores.
