They are a charter company and they operate flights for certain cargo companies. I think they operate flights on behalf of Purolator, Emory, and the U.S Postal service. In addition, they operate passenger charters for tour operators. At one time they operated public charter flights from Sanford, FL to points in the Northeast U.S. Also, they did scheduled service briefly from Detroit to Las Vegas and from the west coast to Honolulu. They have operated DC-10's, 727-100's/200's, and DC-9's. They are based at Dallas Love Field and I think they call themselves Rustler or something like that on the radio.
