Felixstowe F3 Flying Boat

 The Felixstowe F3 was a development of the F2, being larger and less maneuverable than its predecessor, it was not well liked by crews despite its greater range and greater bombload capacity. About 100 were produced during WW1 and it became the RAF's standard postwar flying boat.

 In 1920, the Canadian Air Board used one during its experiments in Trans-Canada passenger and mail service, flying from Riviere du Loup to Winnipeg.

The Portuguese Naval Aviation used one for its first flight from Portugal to Madeira in 1921.
