because unlike anywhere else in many ways we have really thrashed these issues out. so, when i sat down with the malaysian prime minister, i'm remembering what you and i have talked about so many times. i really needed to know when the transponder was switched off. when the acars stopped, been disabled, when the left turn happened, what did malaysia's military see? >> now, the military radar, the radar has some capability. it tracked an aircraft which did a turn back. but they were not sure whether it was mh-370. what they were sure of was that the aircraft was not deem to be hostile. >> no planes were sent up on the night to investigate.
