You’ve probably seen the viral footage of a guy in a gray suit flying alongside a Boeing 747 over Dubai. It looks fake. Even in high-definition, pictures of jet packs often trigger that "uncanny valley" response where your brain screams CGI. But the crazy thing is, we’ve actually had this technology since the 1960s. It just didn't look like the movies.
Look at the old photos of the Bell Rocket Belt. It was this clunky, hydrogen-peroxide-fueled backpack that could only stay in the air for about 21 seconds. Twenty-one seconds! You could barely clear a parking lot before the fuel ran dry and you came crashing down. That’s the reality of the "jet pack" history most people ignore. We want the Rocketeer, but for decades, we just got very expensive, very loud hops.
The Evolution of Pictures of Jet Packs
Modern photography has finally caught up to the dream, but the tech has split into two very different camps. First, you have the "jet suits" popularized by Richard Browning and his company, Gravity Industries. If you look at pictures of these setups, they don’t actually put the engines on the back. Not primarily, anyway. Browning puts micro-gas turbines on the arms.
It looks like a human tripod.
By using his arms to vector the thrust, Browning achieves a level of stability that the old backpack-style units never could. But it’s exhausting. Imagine doing a push-up while five jet engines try to rip your arms out of their sockets. That’s why you’ll notice in almost every professional photo of a Gravity suit, the pilot has massive forearm and shoulder definition. It’s a physical feat as much as a technical one.
Jetman Dubai and the Fixed-Wing Myth
Then there’s Yves Rossy, the "Jetman." When you search for pictures of jet packs and see a guy soaring at 150 mph over the Swiss Alps, you’re usually looking at Rossy. But here’s the catch: he isn’t wearing a jet pack in the traditional sense. He’s wearing a rigid carbon-fiber wing.

He can’t take off from the ground.
Rossy has to jump out of a helicopter or a plane to get started. His "pack" is really a wearable airplane. This is a crucial distinction that most clickbait articles miss. One is for hovering; the other is for high-speed transit. If you see a photo of a pilot standing on a lawn and then taking off vertically, that’s likely the JetPack Aviation JB-series. David Mayman, the CEO there, actually flew a JB-9 around the Statue of Liberty back in 2015. That was a landmark moment because it was the first time a "true" jet pack—one that fits in a suitcase and takes off vertically—was proven to be commercially viable for demonstrations.
Why Do These Photos Always Look So... Weird?
Ever wonder why most pictures of jet packs feature the pilot over water? It’s not just for the cool reflections. It’s a safety requirement.
If an engine fluffs out at 50 feet, you want to hit Lake Geneva, not a concrete pier. This is also why you see so many "water jet packs" or flyboards in vacation photos. Those aren't real jet packs; they're just nozzles attached to a jet ski hose. They’re fun for tourists, but they aren't the frontier of aviation.
The real engineering hurdle has always been the power-to-weight ratio. Gas turbines are incredibly thirsty. To stay in the air for more than ten minutes, you need a lot of fuel. Fuel is heavy. More fuel means more weight, which requires more thrust, which burns more fuel. It's a vicious cycle.

- Energy Density: Batteries aren't there yet. An electric jet pack would be silent and amazing, but the batteries would weigh as much as a small car to get the same flight time as a gallon of kerosene.
- Heat Management: You are essentially strapped to several blowtorches. The thermal shielding required to keep a pilot's back from melting is a feat of material science.
- Control Systems: Human beings aren't naturally stable in the air. We don't have tails or rudders. Modern suits use sophisticated software to help "balance" the thrust, but it still requires hundreds of hours of training.
The Military Reality vs. The Instagram Dream
The British Royal Navy has experimented with Gravity Industries' suits for "visit, board, search, and seizure" (VBSS) operations. You can find photos of Royal Marines flying from a rigid-hulled inflatable boat (RHIB) onto the deck of a moving warship. It’s impressive. It’s also incredibly loud.
You aren't sneaking up on anyone with a jet pack.
The acoustic signature of a micro-turbine is a high-pitched scream that can be heard from miles away. This is the "dirty secret" of jet pack photography—it looks peaceful and majestic, but the reality is a deafening roar that requires heavy-duty ear protection. For the military, the use case is niche. It’s great for getting a medic to a wounded soldier on a cliffside, but as a stealth insertion tool? Forget about it.
What Most People Get Wrong About Jet Pack Safety
There’s this persistent myth that if the engines fail, you just glide down.
Nope.

In a true jet pack (non-winged), you have the glide ratio of a brick. If the turbines stop, you drop. This is why companies like JetPack Aviation have worked on rapid-deploy parachutes that can fire even at low altitudes. But even with a chute, a failure under 30 feet is going to hurt. A lot.
Look closely at the gear in pictures of jet packs. You’ll see fire-retardant flight suits (like Nomex), helmets with integrated comms, and often, specialized boots. This isn't just for the "look." It’s because the exhaust gases can reach temperatures that would instantly ignite standard polyester clothing.
Actionable Insights for the Future of Personal Flight
If you're looking to actually get into this world, rather than just scrolling through images, there are a few things to keep in mind.
First, the "experience" market is growing. You can actually book training days with Gravity Industries in the UK or US. It’s expensive—thousands of dollars for a few minutes of tethered flight—but it’s the only way a civilian can legally and safely get off the ground right now.
Second, watch the development of "heavy lift" drones. Many experts believe the future of the jet pack isn't a backpack at all, but a platform you stand on. This is technically an "eVTOL" (electric Vertical Take-Off and Landing) vehicle. It’s safer because it has multiple redundant rotors. If one motor fails, the others can compensate. With a jet pack, if one of your primary turbines goes, you're spinning into the ground.
- Check the credentials: If you see a "jet pack" for sale on a random website for $5,000, it’s a scam. Real units cost upwards of $250,000 to $450,000.
- Regulations: In the US, the FAA classifies many of these as "Experimental" or "Ultralight." You don't necessarily need a pilot's license to fly some of them, but you do need to follow strict airspace rules.
- Physical Fitness: You need core strength. If you can't hold a plank for two minutes, you probably can't stabilize a jet suit.
The dream of the jet pack is alive, but it's transitioning from a "look at this cool photo" novelty into a specialized tool for search and rescue and high-end entertainment. We're still waiting for the "commuter" version, but the pictures we have today prove that the physics is settled. We can fly. We just have to decide if the noise and the cost are worth the view.
To understand the current state of flight, track the progress of the Zapata Ezfly. It’s basically a Segway for the sky. It uses the same turbine tech but places the pilot on a stable platform, making it much easier for the average person to control. This is likely where the "pictures of jet packs" will head next: more stability, more safety, and hopefully, a slightly lower price tag.
