What PTT, I have one on the boom of my headset, if in fact it has been established that the pilot was the one that actually made those transmissions and not the passenger seated next to him., in the 5 of the 9 airborne seconds. it's clear in my mind that the aircraft was not controlled from the moment takeoff power was set. A runway excursion on this runway in this class of aircraft is extraordinary in itself. I can hardly wait for the final report, it was completed in February and a ninety day right of response from the parties is required, so expect it to be released about mid may. I look forward to being substantially corrected.
