The Head in the Abutment - S11-E19
Character mistake: Hodgins flies a decapitated human head via drone all the way from the crime scene to the Jeffersonian. A distance of several miles over city and urban landscapes. This would comprise all the evidence and be a massive risk to public health. Dr. Hodgins would know how much it would mess up the evidence since his area of expertise is particulates, and insects, both of which would be compromised. (00:28:30)
The Head in the Abutment - S11-E19
Continuity mistake: After Hodgins asks for a drone we see Booth and Bones driving over a bridge. Camera cuts to inside the car and they are now in the middle of a town.
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.
