TAG Airlines
TAG Airlines was a small airline serving Downtown Detroit, Michigan from 1957 until 1970.History
It was founded by William Knight in Cleveland, Ohio as Taxi Air Group in 1955, was then sold to Ross Miller, merged with Illini Airlines in 1957 and definitely renamed.
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. The cause of the crash was found to be a fatique crack in a fitting in the wing root resulting in failure of the right wing.
