Just about every well-known UFO story is billed as among the best documented and most believable. Well, they can't all be right, and certainly some documentation is better than others. UFOlogists' favorite supporting documentation is declassified government communiques that mention the UFO, and one famous case has about as much as any other. It happened in 1976 in the skies over the city of Tehran, Iran, in the dark just after midnight. Not much Iranian documentation survives due to the revolution that happened soon after, but the United States Air Force and Defense Intelligence Agency gathered enough written material to make the Tehran 1976 UFO one of the creepiest, and most menacing, in all of UFOlogy.

The story goes that sometime before midnight on September 19, four Tehran residents began telephoning the local Mehrabad airport stating that they saw a bright light in the sky. Mehrabad's radar was under repair and was not operational, so General Yousefi phoned Shahrokhi Air Force Base at Hamadan, 275 kilometers west southwest of Tehran. They showed nothing on radar. Yousefi went outside and saw the bright light for himself. He then ordered a McDonnell Douglas F-4 Phantom fighter plane, piloted by Lt. Yaddi Nazeri plus a backseat weapons officer, to have a look. It took off from Shahrokhi an hour later at 1:30am. Once Nazeri reached Tehran, he reported losing all instruments and communications, so turned around and returned to base, and reported that his instruments came back once he did so.

A second F-4 was launched at 1:40am, piloted by Lt. Parviz Jafari. Jafari acquired radar lock on the bright object at a range of 27NM. According to the F-4's radar, the object had a signature similar to that of a KC-135 Stratotanker. Jafari reported that its lights consisted of alternating strobes of blue, green, red, and orange, so fast that all four were visible at once.

The F-4 pursued the object to the south of Tehran. It dropped another bright object out, which Jafari believed to be heading straight for him, and he attempted to engage it with an AIM-9 Sidewinder infrared guided missile. But upon doing so, he lost all communications and his weapons console. He turned away, and saw the second object apparently rejoin and merge with the first object. Moments later another bright object came out and went straight down into the ground, leaving a bright trail, and lighting up a large 2-3 kilometer wide area.

Jafari prepared to land at Mehrabad rather than return to Shahrokhi, and during approach experienced further intermittent communications and navigation failures. A commercial airliner in the vicinity also reported communication failures, but did not see anything.

The next day, Jafari and his backseat officer were taken out in a helicopter to have a look at where they thought the light hit the ground. Nothing was found, except they did pick up the beeping from a radio transponder. They homed in on the signal to the vicinity of a house, where the occupants knew nothing except they'd heard a loud noise and a bright flash of light during the night. And that's where the story ended — lots of strange events, and no explanations.

How do we know all of this? Because the Iranians told us. Following the incident, Iran invited the USAF section chief, Lt. Col. Olin Mooy, to a debriefing. The story as just given came from Mooy's official "Memorandum for Record" based on his notes. Mooy's memo was never deemed important enough to classify, and in fact was published in the United States two months later by UFO Investigator, the newsletter of the civilian UFO enthusiast group NICAP.

Iran was a relatively peaceful country in 1976, and open to Westerners. The first rumblings of revolution were still at least a year away. Among the American expats living in Iran were engineers from various contractors who supported the 225 F-4 fighter planes the United States had sold to Iran over the previous decade. And, of course, just about every other guy you'd see on the street who looked American was probably working for the CIA in some capacity or another. So we had really good eyes and ears into the machinations of the Iranian government, and a tight working relationship with their military.

Over the years, most of the story's basics have stayed pretty much the same, even when it was dramatized on a 1994 episode of the TV series Sightings. Sightings got a number of details wrong, including stating that Mehrabad's radar was operational, and that it indicated the object was as large as a KC-135 Stratotanker. In fact radar signatures do not indicate an object's size at all; only the strength of the reflected signal. Sightings also described all the events from the context of a presumption that the light was a hostile and intelligently guided alien spacecraft, using language like the jamming was turned off as soon as the F-4 was "no longer deemed to be a threat", and referring to the light as a "craft" or a "mother ship".

Along with Col. Mooy's memo, the USAF published a narrative titled "Now You See It, Now You Don't" about it, which was classified, and was only released in 1981 following a Freedom of Information Act request.

The case leaves us with six elements that are difficult to explain. First, the classified US military documents. There would not be classified documents if nothing extraordinary had happened. Second, the persistent sighting of the mother ship, the main light that was constantly visible and was observed by residents, by Yousefi, and by the pilots. Third, the selective jamming of communications, electronics, and fire control systems, which remains (to this day) beyond known military capability. Fourth, the radar lock obtained by the second F-4, indicating a solid flying object. Fifth, the bright missiles, first the one that shot out toward the second F-4, and second the one that descended to the ground with a flash. And sixth, the beeping transponder. Let's look at these one at a time.

Classified Documents

First, the classified "Now You See It, Now You Don't" document. As mentioned, this was a narrative, told as a dramatic story, and was hardly in the nature of an official government document. Yet it's often waved by the UFOlogists as compelling evidence. It was actually an editorial in the typed, mimeographed newsletter of the United States Air Force Security Services quarterly MIJI newsletter (MIJI standing for meaconing, intrusion, jamming, and interference). Because this service requires a security clearance, their newsletter is protected as well. There is nothing especially interesting about the actual article; it's just a dramatized retelling of the same information in Col. Mooy's memo, offered in the newsletter as a curious editorial on the subject of jamming and interference.

The Mother Ship

Second was the mother ship, that persistent light in the sky that prompted the phone calls, aroused Yousefi's curiosity, and led the pilots on their merry chase across the skies. We don't know what this was. Journalist Philip Klass suggested that it was the planet Jupiter, an explanation echoed by aerospace researcher James Oberg. Many UFOlogists have dismissed this explanation saying that Jupiter's direction in the sky was 90° wrong, but I found two reasons to give this suggestion some credence. First, the direction is not wrong. The F-4s were scrambled to northern Tehran, not to the light. Once they arrived, they saw the light just where Jupiter would have been. Second, Yousefi and the telephone witnesses all described the light as similar to a star but much brighter. Considering the fact that Jupiter was in the sky, my own conclusion is that it's almost certain that Jupiter was responsible for some percentage of what was reported that night, though not necessarily everything.

Jamming & Electronics Failure

Third was the apparently successful jamming of communications and radar equipment, that one would think should have concerned the Americans and the Iranians equally. In 1978, Klass dug deeper into this. He was not able to get any information from any Iranian sources, but he did track down several American civilian contractors from Westinghouse and McDonnell Douglas who were involved in the incident. The Westinghouse tech at Shahrokhi confirmed that only the second F-4 was reported to have experienced any electrical problems during the flight; the first F-4 was never sent in for maintenance. The McDonnell Douglas tech at Shahrokhi noted that the second F-4 had a long history of intermittent electrical outages that the IIAF had never been able to fix. He was personally called in to adjust that F-4's radar about a month after the event. Both techs stated that the Shahrokhi base was notorious for low quality work and poor record keeping.

So we have reason to expect that Jafari's F-4 would have had electrical problems regardless of whether he was under attack by a UFO or not, and we have conflicting stories about whether Nazeri's F-4 had any problems at all or not. Only Jafari was present at the official debriefing; Nazeri never made any known official report until he had moved to the United States and appeared on the Sightings TV show.

Radar Lock

Fourth is the compelling radar lock obtained by Jafari's backseat weapons officer. Surely there had to be something up there. Maybe there was; most of what these pilots did was to intercept enemy MiG-25 fighters on surveillance missions, whether Jupiter was in the sky or not. But there were also two other possibilities. Note that Jafari's radar was known to be defective, or at least in need of adjustment. The same McDonnell Douglas supervisor noted that the weapons officer "could have been in manual track or something like that and not really realized it." Whichever of the three possibilities was true, it's not necessarily a fact that a radar lock meant something was there. Maybe there was; maybe there wasn't.

UFO "Missiles"

Fifth were the bright objects that Jafari reported came at him, and that shot straight down into the ground. Twice a year, the Earth's orbit takes us through the debris trail left by Halley's Comet, causing meteor showers. We also pass through various other clouds and trails at the same time each year. In his 1984 book Meteor Showers: A Descriptive Catalog, astronomer Gary Kronk studied years of annual meteor data up through 1980. On September 19, we are at or near the maximums of two minor annual showers, the Gamma Piscids (PIE-sids) and Southern Piscids, and at the tail end of a third shower, the Eta Draconids. There was more than enough expected meteor activity to account for all of the reports of falling lights and rapidly moving bright objects. Some UFOlogists have attempted to connect the Tehran sighting with several other sightings of speeding bright lights that same night across the Meditteranean, suggesting that the "mother ship" must have been speeding all around the region. Since there were meteors falling worldwide that night, such sightings are exactly what we should expect to see, mother ships or not.

Klass noted several cases where experienced night pilots have taken unnecessary evasive maneuvers to avoid meteors that they mistook for aircraft. Another telling detail that Klass learned from the American technicians is that the Shahrokhi pilots never flew at night; that these two night sorties chasing the UFO were the only known night flights during the whole time the technicians were stationed there. According to Col. Mooy's report, the pilots reported that landing at Mehrabad was difficult because they were having trouble adjusting their night visibility.

Beeper

Sixth was the beeping transponder located by Jafari and the helicopter crew the next day, apparent physical evidence of intelligent technology. And so it probably was. Col. Mooy noted that the beeping transponder appeared to be from an American C-141. These large transport aircraft carried such transponders designed to be released in the event of a crash, but they'd been having problems with the beepers being ejected simply by turbulence over the mountains just north of Tehran.

Once we look at all the story's elements without the presumption of an alien spaceship, the only thing unusual about the Tehran 1976 UFO case is that planes were chasing celestial objects and had equipment failures. There have been many cases where planes had equipment failures, and there have been many cases where planes misidentified celestial objects. Once in a while, both will happen on the same flight.

A common way for UFOlogists to analyze stories such as this one is to use a process of elimination to show that it wasn't a star, it wasn't Jupiter, it wasn't a meteor or an aircraft, therefore we're left with the only thing it could have been: an alien spacecraft. The problem with this reasoning is that it's exactly as valid as using a process of elimination to show the only thing it could have been was the fiery chariot of Elijah.

Neither, in fact, is a process of elimination the proper way to examine such stories. We want to know what it is, not what it isn't. And, in this case, we don't have enough information to know what it is. So even if any of the six elements is not otherwise explained, all we're left with is "I don't know", not "I do know and it was an alien spaceship." What was the Tehran 1976 UFO? I don't know, but there's insufficient evidence to convince me to get excited about it.

So, why did the US military investigate this encounter?

I thought they didn't do this type of thing since Bluebook closed.

Marko, what is needed is proof that cannot be dismissed so easily, in this example we have pilots who hardly flew at night in their career, possibly with adrenaline pumping, piloting aircraft that have doubtful serviceability. Humans are fallible and eye-witness testimony can be wrong, that's why sceptics need something more than anecdote, they need physical evidence.

Billions of humans on the planet, decades of study and no proof of UFOs existing as anything other than perhaps a meteorological phenomena.

Most UFO enthusiasts seem to think that UFOs are alien piloted, with no proof for it. The reason sceptics can explain away the alien hypothesis belief is because the evidence is flimsy. When an alien lands at Buckingham Palace or the White House, in front of thousands of people and TV crews, leaving evidence of interaction, then they have some evidence that most sceptics would be willing to accept or investigate. Sure some cynics will still claim it was a mass illusion and hysteria or a Illuminati conspiracy or something, but fringe folks will always be there - at either end of a debate.

@ Johnny Doe, from what I read the US really only sat in on interviews and had no in depth investigation themselves. Besides, the US having an interest in a UFO encounter doesn't make it any more valid. Pilots been reporting strange things since they took to the skies, it's common sense to investigate and see if it is just something psychological or perhaps of defence significance.

It makes sense for the military to investigate any form of UFO in the interest of national security, however, they claim not to after Bluebook. So, why would they not look into UFOs, and why lie about not looking into UFOs?

Conflicting evidence from this website. It should be noted that Klass only interviewed Americans, who are actually the one's who are accused of trying to cover up the information of UFOs in the first place.
"The Westinghouse tech at Shahrokhi confirmed that only the second F-4 was reported to have experienced any electrical problems during the flight"
However Jafari's own words conflict with the American source, as seen in his statement at the national press club. (Google it).
What are the details of the "long history of intermittent electrical outages" the F-4 experienced. Was there a history of losing all communications and use of the weapons console? Or is the lack of any detail that part of the "poor record keeping".

The link you provided also stated that a "commercial airliner in the vicinity also reported communication failures", which backs up the claim that it may have been a result from the UFO.
The link you provided also states that "radar signatures do not indicate an object's size at all," does anyone know if this is true? Not that it matters, as the visual sighting did confirm the radar data.

Johnny Doe,
I don't think they're lying about not investigating UFOs. The military, of any country, has a habit of only answering the question they are asked, so the reply was probably something along the lines of 'since the closure of Project Blue Book we no longer have a department dedicated to investigating any and all UFO sightings.'That doesn't preclude them being interested in, as you said, anything that might have a bearing on national security. A sighting by the air force of a friendly nation in a volatile part of the world would certainly fall into that category.

Darren.
So if the 'commies' decided to attack your country with their own super secret technology, the military would just ignore any reports made from any civilian under attack? That's kinda lame for an organisation set up to protect us.

The theories from this website are as follows.
The bright multi-coloured "burning object" was Jupiter, although I have never seen Jupiter flashing different colours, even when on the horizon. Have you?
Nor have I ever seen Jupiter "jump 10 degrees to the right." Have you?
The smaller object that came from Jupiter were merely comets. Although the comet suddenly appeared from Jupiter and headed straight for him. Do comets act like this?
The radar may have been faulty, or perhaps the operator was in 'manual track mode', but didn't know that it was on this setting, although visual sightings backed up the radar data.

So basically according to OP, the Iranian pilots are just dumb idiots who were attacking Jupiter and some comets?

Hey Johnny,

I didn't respond to any of your other points because I don't know the answers and I'm not going to respond to them now for the same reason.

Just to reiterate the point I did make : what kind of sightings are the USAF going to be more interested in? Cletus claiming he's been anally probed by Martians? Or Air Force pilots seeing something strange in the sky?

Darren, Liverpool, UK
December 08, 2012 12:07pm

LOL, obviously the pilot.
But still, my point stands.
If the enemy wanted to attack your country, all they'd have to do is attach some flashing lights to their own super secret technology, and enter your country freely.

You'd have civilians including police officers, ringing in to say there are UFOs flying around, and what would the military do?
"We don't investigate UFOs, sorry."

If the enemy wanted to attack your country, they'd attack your country. If their 'super-secret technology' enables them to enter your airspace without you noticing you'd probably best surrender now.

Fortunately, all they seem to want to do is fly around playing silly buggers, frightening people in rural areas, so they're probably not that much of a threat.

Skeptics often have equally strong beliefs in their teachings and the strings of cherry picked 'facts' to support their beliefs as do religious people to support their chosen doctrines.

A lot of the source data for this article comes from P.Klass, and it is treated as fact.

My point is that P. Klass has been shown to state 'facts' that have in their favor evidence no more verifiable than the kind of anecdotal evidence that skeptics often claim ufo researchers use.

Do some balanced research into him.
