I would love to see a real EM Drive but it is impossible to believe an experiment with external power supply lines attached. Electric motors operate by utilizing the forces that exist between current carrying conductors. Two wires will always push or pull against each other when they carry current and this effect must be eliminated in order to prove drive force.
Why does the experimenter not use some form of shielded on board battery for power? A short duration test might be possible especially if they wish to convince many skeptics.

Would you expect a normal rocket to behave in the same manner if it had to push the aether out of its way? Why would that not require both effects to be present thereby changing the reaction mass expelled by the standard rocket? How would you detect the bow wave or other mass-equivalents to prove they exist? Something must contain the energy that was lost due to operation of the drive and it should be measurable. Then, you will need to modify Special Relativity in order to detect the true absolute reference frame of the universe.

If so, and the EM drive is moving in aether, then leaving a wake (bow wave, eddy turbulence, kelvin wake, etc) also leaves a mass-equivalence. From: David Roberson Good argument.
