Abydos Helicopter, Jet, UFO and Glider: The modern internet - and possible "ancient alien" - myths surrounding a digitally cleaned image of re-carved and eroded hieroglyphs floating around have reached ridiculous levels (see list of UFO facts at the bottom of this post);
Note: What we seem to have here is a modern Apache helicopter and a couple of spaceships from the Jetsons. So are people imagining an Apache helicopter existed in the past along with cartoon spaceships that suddenly came to life from a sci-fi cartoon series?
The explanation is rather simple and concerns a common practice in Ancient Egypt of re-carving/re-using hieroglyphs;
Info for video below: The initial carving was made during the reign of Seti I, and the stone was later reused during the period of Ramesses II with one carving being on top of the other. This palimpsest effect coupled with erosion creates the carving in situ. Erosion of the stone surface is evident elsewhere in the temple. Some of the filling has fallen out in places where the older and the newer inscriptions overlap, which produces unique and odd-looking hieroglyphs.

Next, we discover that while the above carving is just mistaken and is interpreted, we actually do have a couple of strange objects that indicate someone or some culture at some time, for at least a short period, might have had attained flight. The path I'm following starts in Egypt with the Saqqara bird and then assumes some of the ancient Egyptians migrated to the Americas - before and after the invasion of the Asian hordes (with the gods Indra/Zeus) that ended the bronze age civilization and pushed us into a 1-2 thousand year dark age - and continued there till there civilizational offshoot/colony also fell. Along the way, scientific advances, lost in library burning in the age of chaos that followed in the old world, may have continued in some far off colony. Here is the evidence;
Wikipedia: The Saqqara Bird is a bird-shaped artifact made of sycamore wood, discovered during the 1898 excavation of the Pa-di-Imen tomb in Saqqara, Egypt. It has been dated to approximately 200 BCE, and is now housed in the Museum of Egyptian Antiquities in Cairo. The Saqqara Bird has a wingspan of 180 mm (7.1 in) and weighs 39.12 g (1.380 oz). Its purpose is not understood because of a lack of period documentation.

Did an Ancient Egyptian colony in the Americas (or somewhere in that area) eventually attain flight?
A 1500 year old pre-columbian artifact in the shape of a modern aircraft is tested for flight worthiness.

Note: Having a culture, or even city, with flying machines would certainly explain the desert art called the Nazca Lines that wasn't noticed till we too had flying machines of our own.
We know there was famine, disease and war in the old world. We also know there was an invasion on barbaric hordes in the ancient world, around 1177 BC, that destroyed the bronze age civilization (probably the result of displaced peoples from areas turned to desert or from floods and other natural disasters or wars etc.). Maybe people from more developed cultures (with pottery, books, boats, ideas etc) fled east, west and over the ocean looking for a more peaceful life? When Persians fled the Greeks into India there was a flowering of sculpture and a new Golden Age in India, Why not somewhere else? We do know there have been many inventions throughout history that were lost and in some cases rediscovered and in some not.

Top 10 Lost Technologies We Really Could Use Today
It is unclear how advanced technology got in the ancient world, all we can be sure of is that all libraries have been burnt, so all the records are lost and the civilizations that may have flowered into something out of a sci-fi movie, if even for only a few decades or a few hundred years - is our 10s of thousands of years of history - are long gone and even its remains have turned to dust. All that remains are these stone monuments and a few pieces of knowledge and artifacts that have survived through the millenniums of war, migrations and just getting rid of trash.
How can anyone say one culture couldn't have made a plane at some point before falling as all human civilizations or cities have fallen before it. There is still alot more to learn and discover.
Note On Vimanas (Indian "Flying Machines"): To me most of the stories of the vimanas sounds like more sophisticated versions of Pegasus (the flying horse with wings) and Mount Olympus (Heavenly abode of the Gods). Instead of horse, chariots and boats and buildings become the flying things;
This is clearly a land based building VISUALIZED has having the ability to fly. Its like imagining a carpet can fly in the Arabian Nights. Its an easy enough leap for any human to make, all they have to do is extrapolate from seeing a bird fly.
Pushpaka vimana depicted three times, twice flying in the sky and once landed on the ground.
Boats that can fly. No concept of aricraft. i.e. even if the story refers to real events then the flying was made up or no one ever saw the flying ships passed down through legend.
Ravana rides his Vimana, Pushpaka.
Same as above.
This next one is obviously a con (its not even old!);
An illustration of the Shakuna Vimana that is supposed to fly like a bird with hinged wings and tail.
i.e. A boat with the wings of a bird. Simply a ridiculous idea. But not something a child can't some up with. Its like imagining a horse with wings. Or a pig that can fly. Not hard thoughts for a person to think.
The test of a Vimana on the Ancient Aliens show conveniently leaves out which text the dimensions for the craft are taken from. What we seem to see here is an early 19th century balloon/blip;

An aerospace engineer at UC-Irvine tests an aircraft model that was built using measurements from ancient Hindu texts. Ancient astronaut theorists suggest the texts also contain information on how to build advanced spacecrafts in this clip from Season 12, Episode 11, "Voices of the Gods". #AncientAliens
Also, this doesn't look like the pictures of confirmed UFO/UAP sightings we got from the US military.
