Double Trouble in the Panhandle - S4-E12
Revealing mistake: At the end, the stunt double for Bones is visible when she falls off the high wire. (00:39:15)
Revealing mistake: After speaking to the children the victim used to look after, the scenery outside the car shows the car is going forward when we see Booth but when the camera is on Bones, the background is going backwards. (00:17:50)
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.
