Some people have reported that this video is a fake and was even admitted to be a fake by jmart714. However the following was posted by jmart714 on the www.alien-ufos.com form on August 14, 2009:
It's not fake you guys. I uploaded the video under a different name because I was afraid of the truth behind the video. Here is the story below.
The airplane was approaching Davis Monthan Air Force Base in Tucson Arizona at approximately 4:15PM MST on August 8th, 2009. We first witnessed the object hovering in a locked position, southwest of the base. We thought it was a balloon, until it dropped in elevation a few thousand feet in less then a second. At that point I ran inside and grabbed my digital camera and rushed outside in time to catch the object approaching the airplane from behind. Unfortunately the microphone barely works on the camera, from being dropped so many times, so you can't hear much. But at least there is a little. The object made no sound, completely silent.
There was an attempt to take the video to the media, unfortunately, every affiliate rejected the video due to lack of evidence. There was no report in the city of a missing airplane, nor did the Air Force Base report anything missing. Many of the news affiliates did confirm that they had received calls on August 8th from various sources, claiming they had seen a UFO. They said that they receive calls on a regular basis dealing with UFOs all the time, as well as many hoax videos, and there was no reason to believe my video was anything different. They refused to believe that the Air Force base would withhold information about a missing airplane.
At this point, I don't care anymore. I know what I've seen, I even captured it on video, and still nobody believes it. Of course there is no missing plane, because the Air Force isn't talking about it. I understand that I have made a mistake in the way I have handled it on the web, but I was scared, what do you expect. I'm tired of hiding. I've never been the type to show anger toward my military, but this is bullshit.
I personally don't know if the video is fake but if it is, it is a damn good job.
