San Diego CA Marine Air Base Ball of LightI am a Marine veteran and I have decided to tell my story about a sighting that I experienced while working on security forces after the attack on 9/11. My job in the Marines was TMO 3112. After the attacks on our nation I was detached from my unit and attached to PMO security forces. I worked the graveyard shift from 1700-0600. I was stationed at Marine Corps Air Station, Miramar, San Diego, CA. The evening of my sighting I was placed on duty, alone, to guard a gate on the flight-line. I can’t remember the exact gate number, I believe it was 15, but I do know that it was at the north end where the c-130s were parked. I had been on Security forces for awhile and I had a routine way of keeping myself alert and awake. It is a severely punishable offence to fall asleep on post. I would take caffeine pills throughout the night and practice drill movements if I felt myself getting tired.On this particular evening I was very alert. It was particularly cold that night, and being alone on post made me very aware of my surroundings. The small shack that was my post was not heated, so I would frequently leave the shack and walk the small perimeter of the flight-line that was my post. On the last of these walks I left my shack and began walking the flight-line. Something above caught my eye. As I reverted my gaze upward, I was astonished to see small, bright, circular, orb hovering about 200 yards above the flight-deck. The object was no bigger than the circumference of my body. I am a female and I stand at about 65 inches. In a flash, it shot down and hovered inches above the flight deck. It hovered there for a few moments, and then just as quickly as it came down, it shot back up into the night sky, and was gone.I was unsure of how to go about reporting it. I logged the sighting in my log book and radioed it in to my command post. I was almost immediately relieved of my duty at that post, by a Staff NCO. I was told that I was tired and needed to go home and get some rest, and to report back for duty the following evening. Now that I have fully performed my contract with the Marine Corps I feel that it is time to tell people other than close friends and family.I did not see little green men, or a flying saucer. I saw what I believe was an unmanned recording device. I have no reason to lie about what I saw and know that what I saw was real, and I hope that with this report maybe another Marine who was guarding another post on the flight-line that night will come forward.((NUFORC Note: Date is 2002 is approximate.
