Philippine naval base sighting of a ufo/uso with binoculars in hand

I was in the Navy and stationed at Cubi Point Naval Air Station.  I worked at Runway Support and was out on the flight line with my binoculars and flare gun for a 4 hour shift at midnight.  
It was approx. 2 am when I saw what I thought was an aircraft coming in over the mountain top.  I had a radio that I then called the air tower with and no aircraft was coming in.  I told the tower what direction I was looking in and that was the last correspondence I had with him.  
The craft was stationary and darted to the right very quickly and then dropped down to the bay and vanished.  I never saw it fly away in any direction.  It went right above the water.  I never saw any lights until I no longer saw the aircraft.  When it was out of sight I could see a brightness coming from the bay lighting the end of the runway.  I drove to the end of the runway and looked into the bay as the light started to dim and disappear.
I talked to my commander the following day about what I saw and he said that they test all kind of things here but he usually has knowledge of the opporation before it takes place and he had not been notified.
Witness indicates that the date of the incident is approximate.  PD
