A naval Curtiss NC-4 aircraft commanded by Albert Cushing Read leaves Trepassey, Newfoundland, for Lisbon via the Azores on the first transatlantic flight.

The NC-4 is a Curtiss NC flying boat that was the first aircraft to fly across the Atlantic Ocean, albeit not non-stop. The NC designation was derived from the collaborative efforts of the Navy (N) and Curtiss (C). The NC series flying boats were designed to meet wartime needs, and after the end of World War I they were sent overseas to validate the design concept.

Albert Cushing Read, Sr. was an aviator and rear admiral in the United States Navy. He and his crew made the first transatlantic flight in the NC-4, a Curtiss NC flying boat.

Trepassey is a small fishing community located in Trepassey Bay on the south eastern corner of the Avalon Peninsula of Newfoundland and Labrador. It was in Trepassey Harbour where the flight of the Friendship took off, with Amelia Earhart on board, the first woman to fly across the Atlantic Ocean.
