Odd red light zigzaging over Yogyakarta, Indonesia

Sometime during 1992, while on a 2-year accompanied assignment to the Indonesian Air Force Academy at Yogyakarta, Indonesia my two sons called my wife and me outside to ovserve a strange zigzaging red light cross the skyline and then disappear in the overcast sky over the house we lived in, without hearing any sound.  The bright light or lights gave the appearance of a large zig zag or Z shape.  I suggested to our sons that it might be some sort of aircraft, and they didn't think that made sense and had been observing it a good while as it approached, before we were called outside into the open patio. None of us heard any sound, which also was strange, since the clouds it disappeared into were not very high.
The report below I just saw reminded me of the event: GEORGIA ZIGZAGGING CRAFT WITH RED BLINKING LIGHTS MORROW -- The witness says, "While unloading supplies at my office 9:45 AM, I saw a strange looking craft on November 13, 2002, that had three blinking red lights." It appeared to hover then zig zag around the sky and eventually diving behind a group of trees. In a few seconds it appeared again off in the distance at an even lower altitude. At the same time another craft with a very bright light and two red flashing lights appeared behind the same group of trees and just seemed to hover there! These lights were not blinking and were rather large lights. My family and I have observed a passenger type aircraft for 8 or 9 months with a extremely bright double headlight that can hover in one place for any amount of time, and turn on a dime! It doesn't have to make a large turn like a regular plane. We watched twenty to thirty minutes. It could be some new type of craft that the military is testing? We do have an Army base nearby. I don't think it is really an UFO. But it is something new we have never seen in the skies over middle Georgia! NUFORC
