When I was younger, I thought UFO sighting reports were bogus.
When I saw one in 1966, while in the USN stationed at a little transmitter site in the Philippines - I believed.
Now that I'm older, I think UFO sightings are bogus.
The story:
I was an electronics tech (ET), stationed at Tarlac Naval Radio Station, PI. The base was on a high plateau, about 24 km out of Clark Air Force Base, the monument to the Bataan Death March was in our antenna field. This was before satellite communications, of course, and so the Nave relied on very high powered radio transmitters to communicate with the 7th fleet. We had some 40 10KW medium freq. 3 - 30 megahertz, 10 40KW, and 3 very low frequency transmitters with 500 foot towers. If there ever was a beacon to home in on, we were it! There was so much radio frequency energy in the air, you'd draw an arc touching anything metal that was not grounded.
We got really busy with the goings on with the Pueblo and Vietnam, they needed more communications capability but had no more room for antennas, so they opened another "remote" transmitter site across the road. A radioman and an ET would work each of the three shifts there. We'd drive over in a jeep at the shift change. It was dark, and after I drove to the main base to pick up our replacements, when I headed back I saw a glow above the low mountain range that was perhaps 2ot 3 miles distant. There were no roads there, just uninhabited jungle between the base and those mountains that were always green, covered with jungle too.
I couldn't understand the yellowish glow, so pulled over and got out of the jeep. I though it must be a fire, though couldn't understand that either, as wet forest doesn't burn. Then, as I watched, a bright orangish yellow appeared slowly, rising up from behind the mountain. I was shaped like a cigar, both ends tapered, or like looking at a "flying saucer" from the side if you like. It slowly crested the mountain and then started moving down the mountain on my side, stopping about half way down. From the distance and it's size, it had to be huge, guessing 500 to 1000 feet wide.
As I watched, there were several bright orange round shaped flashes that occurred on either side of the bright object, no fire or smoke visible, just the flashes. Then the object started moving back up the mountain - at this point I was absolutely flabbergasted - I knew it was no fire, fire wouldn't move back up the hill from whence it came! I jumped back in the jeep and headed back to the Quonset hut barracks to get more witnesses. I ran in yelling to get some people out of bed - herded 2 or 3 guys into the jeep (they thought I was nuts) and drove back towards the rise in the road - the barracks was in a low area with no line of sight to the mountains. As we topped the rise, it was clear that the object had gone back over the mountain and was on the far side, as there was a huge halo of light just like I'd seen before. This time, though, the light slowly fade out.
I was disappointed that they didn't see what I saw, but they DID believe me, for there was no other explanation for the light.
I went to the main radio buildings and got on the phone to Clark AFB, they assured me they had no flights over Tarlac, and further, they had seen nothing abnormal on their radar screens. I knew I'd seen a UFO of some kind. I've heard of swamp gas, but what I saw wasn't that. I'm not a big dummy, but I have no rational explanation for what I saw that night.
