The UFO objects have not changed shape over the years, but more shapes have come to light. Still, the saucer or circular shape is the most typical shape that there is. Rod-shaped, cylindrical-shaped, or cigar-shaped objects are some of the earliest observed ones as well. Triangular- shapes have been observed since the early 1940s. 

The first major incident was the “Battle of Los Angeles” incident in 1942. The “Lubbock Lights” incident from 1952 is another one where four or five Texas Tech professors saw a large array of lights in a triangular shape. 

Triangular-shaped objects

The photograph was taken by a student. It has been studied for decades. There was a hiatus after this till triangular-shaped objects were seen again in the 1980s and have become more common over the last thirty years. The Belgian wave from 1989 and into the early 1990s and the Pheonix lights from 1997 are two of the most prominent examples of triangular crafts, which were immense in size, and showed flight characteristics with multiple dozens of G-force that would kill any human pilot. Still, the saucer or circular-shaped objects have continued to be the most common shapes known. 

Orb-like objects

Some orb-like objects and so-called “walnut” shaped elliptical objects have been seen as well. Many of these have had highly unusual flight characteristics. I want to make a comment here to try to differentiate between what are objects of largely unknown origin, which became more detectable and observed once radar technology came into existence in the early 1940s (which also implies their preexistence). 

And some objects, especially in the last 40 years may be our own, which could be our own invention with the technology we possess now. Or it could also be replicas of other unknown objects manufactured highly secretively by us, possibly through knowledge acquired from some degree of reverse engineering. 

The saucer or circular-shaped objects

The latter group, which may be due to partially realized technology, tends to have far less dramatic flight characteristics. The saucer or circular-shaped objects have ranged in size from speeding bright balls (e.g., Foo fighters), to objects that are few to several meters in diameter, to gargantuan-sized objects, the size of two aircraft carriers.

Japanese Airlines UFO incident

The famous case in mind is the Japanese Airlines incident over the skies of Alaska in 1986. This was investigated by President Reagan’s personal scientific team. 

It had smaller rotating cylindrical objects with some kind of exhaust that showed up in front of the plane, which later on went to merge with a gigantic elliptical object which was estimated to be the size of two aircraft carriers.

It was tracked by radar from at least two different locations, involving both military and civilian radar tracking centers. It registered a massive blip alongside the tiny blip of the plane. The massive blip lacked any transponder signal that is standard for any man-made aerial vehicle, whether civilian or military. 

The 1976 Tehran UFO Incident

The other amazing incident to mention here is the Tehran 1976 incident where a huge luminous diamond-shaped object was pursued by two F-4s of the Iranian Air Force, with a most remarkable encounter with the unknown object displaying technology centuries ahead of ours.

There were two bright disc-shaped objects that were released by this large luminous diamond-shaped object, one of which spun around the F-4, which was in flight at supersonic speed, causing power failure every time the pilot had a lock-on, and then returned back to merge with the large object. 

The object moved incredibly fast, covering tens of miles in the blink of an eye. The luminous diamond-shaped object was seen by several commercial planes as it sped off to the Mediterranean Sea, leaving an infra-red satellite signature of its definite presence in the airspace. 

The pilots, when returning, were shaken, debriefed, and the news reached the Pentagon. As one of the high-level air-force officials from here mentioned, “This case is a classic that satisfies all criteria for a valid study of the UFO phenomenon.”
