TAG Airlines was a small airline serving downtown Detroit, Michigan from 1957 until 1970. Its slogan was "The World's Busiest Airline", and it served airports that were 5–15 minutes from the downtown areas, mainly in Detroit, Michigan, and Cleveland, Ohio. The business closed not long after one of its de Havilland Doves crashed into frozen Lake Erie in January 1970, killing all nine people aboard.
