The test overlayed on the video in the second link suggests that the P63 pilot is attempting to "restart his engine" a second after an alleged "drone" encounter. Seems an ignorant statement to make, and more than a bit of wild speculation. It would be interesting if the air boss and everyone involved in that show-center operation, including the thousands in attendance, failed to see or report the "drone," but a guy in a parking lot shooting pictures with his cellphone, did.
Fortunately, Juan is on the scene to save us (and the NTSB) from going another day without his expert opinion.
