UFO sighting

Sightings of unidentified flying objects (UFOs) or unidentified anomalous phenomena (UAP) have been reported throughout history. Given the potential security and safety risks they pose, as well as scientific curiosity, there is increasing interest in understanding what these sighting reports represent.

Pilots have claimed to see UFOs for decades – sightings usually involve objects flying in a formation or bright lights, as John Chesire, former US Navy fighter pilot and Former Captain, First Officer, and Flight Engineer for several US airlines, says on Quora.

‘I saw one (UFO) many years ago. However, before I explain that one sighting, let me preface by saying that over my four decades of flying for both the military and the airlines, I have indeed seen quite a number of Unidentified Flying Objects (UFOs). Nevertheless, every one of these UFO sighting was soon quickly identified by me or by others later as something easily explainable and mundane, and thus no longer “unidentified”… except this singular one I now describe.

“A real UFO sighting”

‘I was a captain flying a B-737 late at night on a very short leg from Las Vegas (LAS) to Los Angeles (LAX). This was sometime in the 1990s. It was late at night and the more normal heavy air traffic around LAX was greatly reduced at this late hour.’

‘At the time we were early into our descent into LAX via the old Civet Arrival. It was a clear night and a smooth and comfortable flight. Passing through 18,000 feet/5486m we noticed what we thought was another aircraft well off to our left and high above us. We had no other traffic to observe than this one. While we were on perhaps a 30-degree intercept to the final arrival course, this aircraft high and to our left appeared to be on the normal, straight-in course to LAX.

‘We decided this approaching aircraft would not even be close to being a conflict for us since it was well off in the distance. We would intercept the final inbound course well ahead of him. Since he was not a conflict Approach Control never mentioned him to us either.

‘Although this traffic off to our left was on the normally expected radial and altitude for the LAX arrival, one thing caught both my First Officer as odd. We were passing below 18,000 feet in our descent. This is the time and altitude that airliners will normally turn on their landing lights for a “see-and-be-seen” standard collision avoidance procedure.

A strange aircraft

‘However, although this other aircraft was still well above us, he already had all his bright landing lights on. Quietly I wondered to myself why his lights were on so very early. It seemed very odd and I wondered to myself if there was a reason for this.’

He continues;

‘Switching our radios from Center to LAX Approach Control we turned our attention away from that strange aircraft and concentrated on our approach at hand. Nevertheless, I naturally and briefly glanced a few times at our unusual inbound traffic.

Defying physics

‘Right before we made the right turn to intercept the final approach course, I once again glanced up at our traffic. What I saw I would never forget! Those bright lights we thought were from an aircraft on approach suddenly and almost instantaneously moved horizontally across the night sky by maybe 35 to 40 degrees and at a considerable distance! Nothing could move that fast! It defied physics. I turned to my First Officer and asked, “Did you see that?” His eyes were as big as saucers as he said, “I sure did!”

‘There was no craft that I knew of or anything I could ever imagine moving that far and that fast across the sky, and then stopping instantly without any apparent slowing, dead in space. Moreover, there is no man or beast that could ever survive the amount of G-forces both from that extreme acceleration or the almost instantaneous stop. There was no logical explanation for what we had witnessed. There was even no illogical explanation either. To this day decades later I cannot explain what exactly we saw.

Multiple and distinguishable lights, like an airliner’s

‘A few seconds after it had made this astonishing move, it made another much shorter and very quick jump a couple of degrees downward. By this time, we were almost passing through the localizer and we had to turn away from this ‘thing’. As I looked back over my shoulder, I saw it move again horizontally toward its earlier position rapidly, but nowhere near the almost instantaneous movement across the great span we saw earlier. I later wondered if maybe it was the reflection from some kind of searchlight, but it was a clear night with no clouds to reflect upon. Also, it had multiple and distinguishable lights, just like an airliner’s.

‘We never reported this incident although I have thought about it over the years many times. Really what could we say? Besides people look at you funny when you say you “saw something” but don’t know what. It also involves a lot of paperwork too, we assumed. So, we kept quiet. Curiously I do not even remember my First Officer and I ever talking about it later. It was just one of those unexplained things that we could not explain and did not even want to try.’

More crews “had seen something.”

Chesire concludes;

‘Ironically the following week I flew the same flight at the same time but we thankfully saw no UFOs this time. What was very curious though was when we switched frequencies, there was a lot of chatter – something unusual for that usually slow time of night. All we could tell from the chatter was that one or more crews “had seen something.” There were transmissions from several aircraft that said, “Yeah we saw it too.” Then Center or Approach came up and asked each aircraft if they wanted to make a report. In rapid sequence, they all said “negative.” I never did either.’
