The Rocketeer: Jet Packs, Howard Hughes, and the Fantasy of Flight
Some engineering fantasies refuse to die, no matter how many laws of physics, safety regulations, and common-sense objections get in the way. The Rocketeer is one of them. Released in 1991 but set in 1938 Los Angeles, the film wrapped one of the most irresistible technology dreams ever put on screen — personal rocket flight — in polished aircraft, air races, art deco swagger, Nazi villains, and a fictionalized Howard Hughes guarding dangerous new technology. The movie was not a box-office success on release, but it held onto a loyal following and later grew into a cult favorite
Engineering the Impossible
That is part of what makes it perfect for an Engineering the Impossible series. The Rocketeer is not just a superhero movie. It is a love letter to aviation obsession: the kind of story built on speed, daring, elegant machines, and the old belief that one clever invention might let a single human being do something nature clearly did not intend. And in 2026, the property has new life again through IDW’s The Rocketeer: The Island, a new comic miniseries based on an unpublished Dave Stevens outline.
What The Rocketeer Got Right — and Wrong — About Jet Pack Engineering
The movie gets one big thing exactly right: a personal flying machine is thrilling because it is both elegant and absurd. The appeal is not just speed. It is freedom, style, danger, and the feeling that engineering might briefly overpower human limitations. That is why the rocket pack in The Rocketeer feels so plausible even when it is not. The movie knows the fantasy matters as much as the machinery.
Where the film drifts away from engineering reality is in how usable the pack seems. In The Rocketeer, the device is dangerous, yes, but still functional enough to become an adventure machine. Real rocket belts were far less forgiving. The best-known early example, Bell’s Rocket Belt, was demonstrated in 1961 and proved that personal rocket flight was possible — but only for seconds at a time. Bell’s hydrogen peroxide system delivered about 21 seconds of flight, which is enough to amaze a crowd and terrify a pilot, but not enough for the kind of sustained heroics the movie makes look almost practical.
The film also borrows some of its glamour from Howard Hughes, but that part is fiction. Real Hughes was absolutely a giant in aviation and high-speed aircraft, but not because he was secretly building movie-style jet packs. In The Rocketeer, Hughes functions more as a symbol of prewar American invention: brilliant, secretive, wealthy, and exactly the kind of man a pulp adventure would trust with forbidden propulsion technology.
And then there is the darker legend that tends to surface around stories like this: the claim that Nazi Germany had a wartime jet pack called the Himmelstürmer. It is the sort of story that sounds plausible enough to survive online for years. Sleek German engineering, secret weapons programs, desperate wartime experimentation — the myth practically writes itself. The problem is that the historical footing is weak. The strongest debunking trail points not to a solidly documented wartime program, but to a long-running internet myth that spread far more successfully than it was ever proven.
That does not ruin the fantasy. It makes the real story better. Because the first well-documented practical rocket belt came later, through Bell’s mid-century engineering work, not through a confirmed 1930s or wartime German jet-pack breakthrough. That gap between fantasy and reality is exactly what makes The Rocketeer so much fun: it lives in the space where engineering still looks magical because the world has not quite figured out the limits yet.
Could a Real Rocketeer Ever Work?
In the narrowest sense, yes. A real Rocketeer could work, in the same way Bell proved a rocket belt could work: enough thrust, enough control, enough courage, and very little room for error. But if the question is whether a human could fly around with the freedom, duration, and swagger Cliff Secord enjoys on screen, the answer becomes a lot less cheerful.
The first problem is fuel. Rocket propulsion gives tremendous thrust, but it burns through propellant brutally fast. Bell’s Rocket Belt used hydrogen peroxide and still only managed around 21 seconds of flight. That is the central heartbreak of personal rocket flight: the machine can absolutely lift a person off the ground, but not for long enough to become the effortless transportation fantasy people imagine.
The second problem is control. Movie jet packs tend to behave like extensions of the body, almost as if the user instantly develops the balance of a bird. Real systems are much less romantic. The Bell Rocket Belt required careful thrust vectoring and a pilot who could manage a very unforgiving machine. Even small mistakes matter when the entire vehicle is strapped directly to the fragile person it is trying to keep alive.
Then there is heat. Bell’s system worked by decomposing concentrated hydrogen peroxide over a catalyst, producing high-temperature steam and oxygen for thrust. That is wonderful for lift and less wonderful for the person wearing the machine. Movie costumes are designed to look heroic. Real propulsion systems are designed around not setting the operator on fire.
And then, of course, there is landing. This is where many glorious flying-machine fantasies go to die. Taking off is exciting. Flying is cinematic. Landing is where engineering comes back into the room with a clipboard and a deeply disapproving expression. A short-duration rocket belt gives the pilot almost no margin for recovery if something goes wrong. That makes every flight not just a propulsion problem, but a precision-timing problem with gravity waiting impatiently underneath.
So could a real Rocketeer exist? Briefly, yes. Gracefully, less so. The dream was always possible in flashes. The problem was making it survivable, repeatable, and useful enough to become more than a spectacular engineering dare.
The Dream Didn’t Die
The Rocketeer’s fantasy never fully went away. Engineers are still trying to make personal flight real — not in the effortless Hollywood sense, but in the louder, hotter, more expensive, and much more engineering-heavy reality of actual hardware.
JetPack Aviation has continued developing turbine-powered jetpacks, including models such as the JB10 and JB11, with the company describing flight times in the neighborhood of 8 to 10 minutes depending on pilot weight and conditions. A 2021 New Atlas report also said JetPack Aviation had sold two JB-12 units to an undisclosed military customer. That does not mean personal jetpacks are about to replace cars, but it does show the dream is still alive in specialized, very niche form. It is just alive in a way that is much more expensive and far less forgiving than pulp adventure stories ever suggested.
Gravity Industries has taken a slightly different path. Its jet suit sits somewhere between engineering platform, public demonstration, training experience, and spectacular proof that some humans remain committed to making physics nervous. Gravity offers flight experiences and training from its UK base, which says a lot about where personal flight currently lives: not as everyday transportation, but as a real, difficult, high-skill machine that can actually be flown under controlled conditions.
That may be the most Rocketeer-like truth of all. We still have not made personal flight practical for ordinary people, but engineers are clearly not done trying. The dream did not die. It just grew up, got louder, became vastly more expensive, and acquired a much stricter relationship with risk management.
Why Engineers Still Love This Movie
Because The Rocketeer understands something very real about engineers and aviation dreamers: people do not fall in love with technology only because it is practical. They fall in love with it because it is elegant, bold, improbable, and full of promise. The movie is built around a machine that is almost certainly a terrible product and an absolutely perfect fantasy.
It also taps into a very specific kind of engineering nostalgia. The late-1930s world of the film is all airfields, polished metal, stunt flying, gangsters, movie stars, and industrial titans. It imagines a time when invention still looked glamorous and dangerous at once, when a machine could be both beautiful and terrifying, and when the line between pilot, mechanic, and madman was pleasantly blurry. That is catnip for anyone who loves aviation history.
And unlike many tech fantasies, The Rocketeer keeps its impossible machine close to the body. This is not a giant starship or a distant supercomputer. It is one person, one engine, and one terrible idea that somehow works just enough to feel believable. Engineers tend to love that kind of problem. It is intimate. It is mechanical. It is dangerous. And it feels like something that, with enough late nights and enough stubbornness, someone somewhere might actually build.
The Rocketeer’s Legacy
Part of the charm of The Rocketeer is that it never completely disappeared. It may have disappointed at the box office in 1991, but it kept its cult status, and now the character is flying again in a new form. IDW’s 2026 miniseries The Rocketeer: The Island brings Cliff Secord back in a new story based on an unpublished Dave Stevens outline, which is exactly the kind of revival this property deserves: adventurous, strange, and rooted in the original romantic pulp energy that made people love it in the first place.
That makes now a perfect time to revisit the film, not because the world is finally ready for everyone to commute by rocket pack, but because The Rocketeer still captures something timeless about engineering ambition. It asks a question engineers never really stop asking: what if the impossible is only impossible until someone gets the machine almost working?
Bottom Line
The Rocketeer was never really about whether a jet pack was practical. It was about whether engineering could make one human being feel briefly, gloriously impossible. Howard Hughes’ role in that dream was fictional. The Nazi Himmelstürmer story is murky at best. But the real engineering history of rocket belts is fascinating enough without either of those myths. Bell’s 1961 demonstrations proved that personal rocket flight was real — just short, hot, difficult, and not remotely as forgiving as the movies promised.
That is why The Rocketeer endures. It sits right on the line between fantasy and feasibility, where the best engineering stories often live. It reminds us that some machines matter not because they are practical, but because they show us how badly humans want to rise above the limits built into us. And if that takes a polished helmet, a leather jacket, and a completely unreasonable amount of thrust, so much the better.
