Rare, vintage World War II planes have landed in Colorado as part of The Wings of Freedom Tour — but they’ll be taking off soon. The unusual exhibit, which runs through Wednesday at Centennial Airport, includes a B-17 Flying Fortress “Nine O Nine,” Consolidated B-24 Liberator “Witchcraft,” B-25 Mitchell “Tondeloyo” bombers and P-51 Mustang “Betty Jane” fighter.
