We didn't see it appear but it was like we were suspended in time

I was a driver for a command Sgt Major and we were trainning in the desert near Goldstone racting Station and it was about 0130  and we were park looking at a grid map using our red light flashlights and off about 300 yards we saw a oval shape object hovering about, I would say about 200 ft off the ground and it was making a buzzing noise with a bright white light. It just hover for a few minutes. The Command Sgt Major grab the mike on the radio and tried to get ahold of TALK we got our call sign out and a got a reponse from TALK that they acknowlege our radio transmission and the radio went dead, the engine stopped running the black out lights went off and we were dead in the (Water). And  time seem to lapse by and then it took off real fast in a diagle it was going from east to west and just disappeared but before it disappeared it made some unreal turns that startled us. then the jeep was running again like it was before and the radio was working and TALK was calling us and they said they were trying to reach us for about five minutes with no reponse. TALK for which I don't rememmber what it means but that was our HHD, Head quarters and Headquaters Bn Radio center.
