Since currently the oldest world resets to about 1955 and the game already has older planes like the DC-3, DC-4, Boeing 307, and Martin 2-0-2 that go unused, would it be a fun idea for one of the Realistic Worlds to reset to the late 30's, like 1937? That way it wouldn't be too long before aircraft development takes off.
