HARTFORD, Conn. (AP) - Newly released documents show the Connecticut Airport Authority touted how a casino at Bradley International Airport could "capitalize on a captive audience," with more than 17,000 passengers passing through the Windsor Locks facility daily.

The pitch was part of a proposal submitted last year to the Mashantucket Pequot and Mohegan tribes, who are reviewing locations for a proposed satellite casino to help blunt competition from MGM Resorts International's planned casino in Springfield, Massachusetts.

MGM released a copy of the proposal Friday after obtaining it through an open records complaint.

MGM says it shows how the proposed, approximately 200,000-square-foot casino is much larger than suggested by the tribes.

The authority pulled plans in June to locate a casino at its new transportation center, but said there are other possible airport sites.
