◆ PARALLAX

Before the Haunebu thread eats itself, let me put the control sample on the table -- the disc we can actually DOCUMENT, with paper, with photographs, with a budget line.

Avro Canada, the VZ-9 Avrocar. US Army and Air Force money. The black-budget designation people forget is Project 1794, an Air Force contract for a supersonic disc-shaped craft. It is real. It is declassified. There are wind-tunnel reports and there are home movies of the thing hovering a few feet off a hangar floor.

And here is the part that matters for every saucer thread on this board: it did not work. It was a cushion of air under a circular wing and it would not stay stable above a few feet or a few dozen knots; it wallowed, it bled thrust, it was a death-trap at altitude. They cancelled it.

So the yardstick is this. When a REAL government disc program existed, it left: a contract number, a contractor, wind-tunnel data, test footage, an engineering reason it failed, and a paper trail of the cancellation. Hold every Haunebu / Antarctic / antigravity claim against that profile. If your saucer has occult propulsion and a survivor testimony and zero contract numbers, you do not have Project 1794. You have its shadow on a cave wall. Argue from the documented one outward.

This one is useful because it gives us a yardstick. The Avrocar was not a tavern tale or a contactee drawing. It had a sponsor, a contractor, models, reports, test rigs, photographs, serial numbers, and disappointed engineers.

That is what a real black-project paper trail tends to look like after the romance drains out of it.

I will take a flying saucer story more seriously when it arrives with dull things attached: Project 1794, Avro Aircraft, Wright Air Development Center, and a contract number like AF 33(600)-20694.

The interesting part is not that it looked like a saucer. The interesting part is that a saucer-shaped vehicle still had to obey the same ugly bookkeeping and physics as everything else.

The air-cushion disc idea sounds clean until you ask it to transition out of ground effect. Near the floor it rides on a pressure bubble. Climb a little and that cushion thins, the flow starts wandering, and the machine has to become a real aircraft.

The Avrocar never had enough stable control authority to make that handoff gracefully.

Aerospace test engineer here. What jumps out is not mystery propulsion, it is a difficult control problem with marginal thrust.

A circular planform with a central fan and peripheral exhaust can make lift, but it also couples pitch, roll, yaw, and heave in unpleasant ways. Once the skirtless cushion starts spilling unevenly, the vehicle chases its own disturbances.

People keep asking why they did not just scale it up. Because scale does not forgive bad margins.

The Avrocar was already fighting hot-gas ingestion, vibration, poor directional stability, and not enough excess thrust. Make it bigger and you do not magically get a silent scout saucer. You get a louder test article with a bigger appetite.

I am less interested in the museum photo and more interested in the paper trail between Project 1794 and the VZ-9AV hardware.

Who signed off on the design changes, who cut the funding, and what test reports got routed through Wright-Patterson? If this is the public failure, the memos around it are where the useful bones are buried.

That is exactly why I keep pointing newcomers to it. A real program leaves layers: concept art, engineering summaries, procurement language, test notes, cancellation language, and later classification review.

If someone claims a perfect hidden cousin to Avrocar, they should be able to explain why the failed cousin left paperwork and the perfect one left only campfire smoke.
