I was hoping some of you with more knowledge about UFO's than I, could share you view points on this. Has the shape from a traditional saucer to cigars and triangles have a pattern?
For instance, if we look at aircraft from the 1940's and 1950's, they were propeller driven and then we see the emergence of jet aircraft. In is known that the Nazi scientists were developed some flying saucers. In modern times, we have the F117 and B2 which have the triangular shape or a saucer shape depending on your angle of view. Lockheed skunkworks have reportedly designed several flying disc's and other Top Secret projects that are some fifty years more advanced than the aircraft of today. (Discovery Channel "Discovery Hoy")
Therefore, to me it seems logical that if UFO's are really military aircraft, we would see more advanced and changing designs. Kind of like what we are seeing in the various UFO reports today.
If UFO's are really alien in orgin, spanning unknows distances in time and space, I would imagine the shape would likely stay the same year after year.
Any thoughts or other logical conclusions?

Actually, descriptions of UFOs have been fairly constant thoughout the centuries only that they weren't called, 'flying saucers.'

<^?1,500 BC: Pharaoh Thutmose III In Egypt, the Pharaoh Thutmose III sees silent, foul-smelling circles of fire and flying discs in the sky.
Excerpt from an Egyptian papyrus - part of the annals of Thutmose III, who reigned around 1504-1450 B.C.:
In the year 22, of the 3rd month of winter, sixth hour of the day... the scribes of the House of Life found it was a circle of fire that was coming in the sky.... It had no head, the breath of its mouth had a foul odor. Its body one rod long and one rod wide. It had no voice. Their hearts became confused through it; then they laid themselves on their bellies....They went to the Pharaoh... to report it. His Majesty ordered .... [an examination of] all which is written in the papyrus rolls of the House of Life. His Majesty was meditating upon what happened. Now after some days had passed, these things became more numerous in the sky than ever. They shone more in the sky than the brightness of the sun, and extended to the limits of the four supports of the heavens.... Powerful was the position of the fire circles. The army of the Pharaoh looked on with him in their midst. It was after supper. Thereupon, these fire circles ascended higher in the sky towards the south... The Pharaoh caused incense to be brought to make peace on the hearth... And what happened was ordered by the Pharaoh to be written in the annals of the House of Life... so that it be remembered for ever.

216 B.C. Things like ships were seen in the sky over Italy... At Arpi (180 Roman miles, east of Rome, in Apulia) a round shield was seen in the sky.
99 B.C. When C. Murius and L. Valerius were consuls, in Tarquinia, there fell in different places.... a thing like a flaming torch, and it came suddenly from the sky. Towards sunset, a round object like a globe, or round or circular shield took its path in the sky, from west to east.
90 B.C. In the territory of Spoletium (65 Roman miles north of Rome, in Umbria) a globe of fire, of golden colour, fell to the earth, gyrating. It then seemed to increase in size, rose from the earth, and ascended into the sky, where it obscured the disc of the sun, with its brilliance. It revolved towards the eastern quadrant of the sky.
85 BC: From Pliny, Natural History: Book II, ch 34 "In the consulship of Lucius Valerius and Caius Marius, a burning shield scattering sparks ran across the sky."
776 AD: From an old chronicle by W. R. Drake "Those watching outside in that place, of whom many still live to this very day, saw they beheld the likeness of two large shields, reddish in color in motion above the church, and when the pagans who were outside saw this sign, they were at once thrown into confusion and terrified with fear and began to flee from the castle."
1180, A term equivalent to our "flying saucer" was actually used by the Japanese approximately 700 years before it came into use in the West. Ancient documents describe an unusual shining object seen the night of October 27, 1180, as a flying "earthenware vessel." After a while the object, which had been heading northeast from a mountain in Kii province, changed its direction and vanished below the horizon, leaving a luminous trail.
1361, A flying object described as being "shaped like a drum, about twenty feet in diameter" emerged from the inland sea off western Japan...
1387 A.D. In Novr. and Decr. of this year, a fire in the sky, like a burning and revolving wheel, or round barrel of flame, emitting fire from above, and others in the shape of a long fiery beam, were seen through a great deal of the winter, in the county of Leicester, Eng., and in Northamptonshire.
1909* Persian Gulf: Objects described as rotating wheels, which could go under water were sighted and a Danish captain.
* Vietnam, Dong Hui: Fishermen located at the port city of Dong Hui; saw an elongated brightly lit object flying over the community for nearly ten minutes. It then disappeared after plunging into the sea of the cost.
1912 (Triangular UFOs) England, Chisbury, Wiltshire: Charles Tilden Smith reported the following case to the respected British science journal, Nature. For over half and hour Smith observed two fan shaped or triangular 'heavy shadows' cast onto clouds overhead. The clouds were moving rapidly, but the shadows remained stationary in the sky. From time to time the unidentified apparitions varied in size. Smith concluded that two large unseen objects in the west were intercepting the Sun's rays.
1917 Portugal, Fatima: Such phenomena include disks, like an "aircraft of light," described exactly in these terms by the witnesses of the fifth apparition. Also observed were double supersonic detonations, light protuberances, electro-static charges, and moving "stars," mysterious white flowers or snow that dropped down from the "aircraft of light," but disappeared when it made contact with the ground. These descriptions of "snow" or mysterious white "flowers" are quite similar to the descriptions of "angel hair" that are well known from some famous UFO cases. This was accompanied by additional unexplained aerial phenomena, in the form of glowing spheres and disc-shaped objects. A UFO sighting had taken place before a crowd of somewhere between 50,000 - 100,000 people! The story given was that a silver disc appeared just as "the rain stopped and the clouds rolled back, the sun dimmed out and everything took on a gray, opaque appearance". The disc then dove in an erratic, zigzag pattern at the crowd, stopped just above their heads and then slowly maneuvered back into the sky. As it faded from view, the sun brightened and began to shine again normally. A local reporter took a photo of the disc.
1926, * Mongolia: During his expedition explorer Nicholas Roerich and members of his caravan, caught sight of a huge oval-shaped object high in the sky. It had a shiny surface that reflected the sun on one side and moved at great speed north to south.
1927, USA, Nebraska, Scottsbluff: While flying near Scottsbluff, pilot Barney Oldfield finds his biplane flanked by "flying manhole covers."
