Aircraft at the edge.

The most famous aircraft ever built, flown to the edge of their flight envelope — and what was waiting there. Real 3D, real archive film, the original documents.

16–20 minute films · in English and German

A jet pitched nose-up against the oncoming air; the angle between them is alpha RELATIVE WIND α ANGLE OF ATTACK

What the name means

High alpha /haɪ ˈæl.fə/

Pilots' language for a steep angle of attack: the wing pitched up against the air, right at the edge of what it can do. That edge is where every one of our films takes place.

The formula / 01–04

Every film is built the same way.

No channel-of-everything history lessons. One aircraft, one question, one day that really happened — answered from the paperwork.

01

A famous aircraft

An icon you already know — the X-15, the SR-71, the B-52, the F-14 — pushed past the point its designers planned for.

02

One precise question

Not “the history of”. One question you can answer in a sentence — and we do, before the credits.

03

A real, dated day

Every film opens on a day that happened: the date, the altitude, the people on board, in the present tense.

04

The original documents

Flight manuals, test reports, accident findings and the crews' own accounts. Quoted — never invented.

Start with the fastest.

X-15A-2 · 3 October 1967

What Really Stopped the X-15 at Mach 6.7

October 3, 1967. Pete Knight pushes the X-15A-2 to Mach 6.7 — still the fastest a piloted, powered aircraft has ever flown — and lands with the coating burned through and metal melted under the tail.

The engine was fine. The pilot was fine. The airframe was not. From NASA's post-flight inspection and Knight's own pilot report: what really stopped it.

How it's made / four layers

The part that decided it, on screen.

Netflix-grade 3D where the camera can go anywhere, real film where it already went, and the document itself where the numbers live.

Real 3D cutaways

Real aircraft models, opened up to show the one part that decided the day — and when no model exists, we build one from photographs.

The drawing board

Mechanisms too fine for 3D are drawn line by line, the way an engineer would sketch them.

Real archive film

About a quarter of every film is real footage and photographs — NASA, the National Archives, U.S. government film. The day, as it was.

Every number twice

Feet and metres, mph and km/h, °F and °C — on screen, every time. Nobody has to convert in their head.

The rules / every film

No hype. No invented drama.

The real story is dramatic enough. Our job is to get it right.

  • 01

    Every description lists its sources — with publication details.

  • 02

    We say what is not known, instead of guessing.

  • 03

    Illustration is marked as illustration. AI reconstructions are made from real photographs and labelled on screen.

  • 04

    Every 3D model and music track is credited by name.

Coming next / in production

Next to the edge.
