The Skull in the Desert - S1-E17
Continuity mistake: During the scene when Booth and Bones are driving to tell Angela that her boyfriend is dead, the scenery behind Booth jumps suddenly mid shot. Initially the scene is of a wide plain, then suddenly a mountain range appears. This scene was obviously shot on a sound stage, with the scenic background being projected onto screens around the vehicle, an old trick in movie making. It seems that somebody mistimed the loop of the tape they were using. (00:12:30)

Answer: Answering my own question here but, having contacted various people involved in the production of Bones including Kathy Reichs, Hart Hanson, Eric Milligan, and Deirdre Lovegood who portrayed Taffet onscreen I finally have the answer. No-one know how she did it due to her constantly working alone. And she never revealed this information before her death.
