There were many "time travelers" who called Art Bell. Time Traveler Open Line was a regular segment of his show. He would announce the phone number for the open lien set aside for time traveler calls only. He had a call screener who would give you about 15 seconds to convince him that you were interesting enough to be put on the air. Getting on the air had nothing to do with whether or not Art believed that you were a real TT. Art just looked down at the call holding lines, got a briefing on the callers during a commercial break and then Art would decide which line would be the most interesting to put on the air. If it was David Anderson (not John Titor) David was put directly through.
