Licensed balloon pilot here… The only manned balloon for which you don’t need a license (in the US) is an ultralight, weighing less than 155lbs empty.
They do exist, though. They’re commonly called “cloudhoppers”. They are basically a climbing harness, backpack straps on a propane tank, and an overhead flamethrower, all hanging underneath a pup tent.
Edit: you can increase the weight to 254lbs empty if instead of a “balloon”, you build a “thermal airship”. Balloons are considered unpowered aircraft because they have no source of propulsion, only lift. Throw some source of propulsion on board - a small electric fan, for example - and it becomes a “powered” aircraft with a higher weight limitation.
Don’t forget you’re still not allowed in a lot of US Airspace even if you don’t require a license for it.
True. The main airspace restrictions on ultralights that are not on certificated aircraft are a prohibition against flying over congested areas (yellow on a sectional chart), and within the lateral boundaries of Class E airspaces around airports. (You can’t fly an ultralight in the class E airspace around an airport, nor in the Class G airspace underneath that Class E)
Certificated aircraft (including balloons) can be flown over congested areas and within Class E and G airspaces.
The limitations on flight in A, B, C, and D airspaces are similar for both: flight is prohibited without specific authorization arranged beforehand.
Interestingly, if an ultralight somehow received permission to enter Class E(controlled) airspace, they still cannot descend into the Class G (uncontrolled) below it. That Class G is within the lateral boundaries of the Class E, and the controller’s authority does not extend to that airspace.
Incorrect. The vast majority of the airspace over the contiguous United States is controlled, though there is a lot of it where participation in ATC is not necessary for VFR flight. From 1,200 feet AGL up to 18,000 feet MSL you’re in Class E, and from 18,000 to 60,000 you’re in Class A. Above that you’re in Class E again. In some places, usually over some un-towered airports, Class E will extend down to 700’ AGL or down to the surface as marked on sectional charts. Class D airspace, as well as the center columns of C and B airspace, extend to the surface.
Class G airspace pretty much only exists below 1,200’ AGL in most places, I think there are remote areas in the middle of the flyover states and Alaska where the Class E floor is higher because there’s nothing there, but that may be changing with ADS-B and shit.
It is not mandatory to participate in air traffic control to fly in Class E airspace. Laymen tend to use “controlled airspace” to mean “off limits without permission” but that’s not how that works; Restricted areas for example require clearance to enter but exist as a separate concept to the alphabet airspace system.
“Controlled airspace” means some part of the air traffic control system has coverage in that area and can provide traffic separation and sequencing for IFR flights. For VFR it’s a little more complicated; in Class A airspace (high altitude en-route airspace) VFR flight is not allowed. Terminal airspace (Class B, C and D, found around airports) participation in ATC is required for all flights. ATC services in Class E airspace is optional for VFR and is on a “workload permitting” basis.
So. What do I do if I start floating over controlled airspace? I can’t make it go any other way.
Descend and land. You’d have done that long before “starting to enter” restricted air space. Otherwise enjoy your fine and potentially losing your license once the FAA finds out.
It’s like not you can accidentally enter restricted air space. You know you’re going to be entering the airspace long before you get there so there is plenty of time to take action.
Flight planning.
You presume a scenario where you make this realization while you are in the air. In practice, you made this realization hours earlier, and adjusted your flight plan to avoid that problem. You selected a launch site that avoids putting you in that situation.
If I do find myself encroaching on controlled airspace, I could declare an emergency, inform the controller where I am so they can vector traffic away from me, and do what I need to do to get down safely. At the very least, I would expect to do a lot of paperwork, and possibly have my license suspended.
With Class B and C airspace, the boundary is altitude dependent. The outer ring of Class C is 10 miles from the airport. I can fly between 5 and 10 miles of Akron Canton Airport, I just can’t climb above 2500’ MSL while in that area. I generally plan my flights to stay outside 10 miles, with the understanding that I can just stay below their airspace if I happen to get too close.
Small point of grammar: Floating “over” controlled airspace means you are still outside of it. Airspace is 3 dimensional so in addition to having horizontal boundaries, it also has vertical boundaries. Class C airspace for example, which you find around semi-busy airports like Raleigh-Durham International, looks kind of like a quarter stacked on top of a penny, except the stack is 4000 feet tall and 10 miles in diameter. You remain outside of the Class C airspace if you fly directly below the outer “ring.” Or if you fly directly above it. I’ve done both, though I usually make a habit of calling up the approach controller and requesting flight following so that they can talk to me if they need to (“me” being a licensed pilot flying Skyhawks or smaller).
If you are going to fly an ultralight aircraft, you should seek out and receive training about the national airspace system, learn how to read a sectional chart, read things like Part 91, etc. I would advise carrying an aviation COM radio and monitoring local CTAF frequencies.
If flying something like a free balloon, you should know the prevailing conditions before takeoff. If the wind is blowing in the direction of a no no place, just don’t launch. Stay on the ground until conditions for safe and legal flight exist.
How cool, more about cloudhoppers if you’re curious like me. It looks like they start around $23,000, which is a lot considering you can get into paragliding for a lot cheaper than that I think. I would rather paraglide.
Those $23,000 balloons will be certificated aircraft, and will need a licensed pilot, even though they might otherwise qualify as ultralights.
Most ultralight cloudhoppers are homebuilt envelopes with commercial burners and fuel systems. Material cost in the neighborhood of $5000.
My used, complete, certificated system (not a cloudhopper; a regular hot air balloon) was $10,000, including envelope, basket, burners, tanks, fan, trailer, instruments, and a bunch of accessories.
I’m so afraid of heights that my palms are sweating reading that, but that’s an objectively cool hobby

TIL I can walk around with a flamethrower as long as I have a balloon strapped to my back
Pretty much, yes.
Our burners consume raw, liquid propane, at 150PSI to the blast valve. Normally, when liquid expands into a gas, the temperature drops precipitously, and with it, the pressure. However, we feed that liquid propane into a heat exchanger: the coils at the top of the burner. This superheats the propane, allowing it to vaporize easily and rapidly after it passes through the nozzles on the burner ring.
The end result is a 30’ flame.
You’d want to fashion some sort of sling and stock to handle that burner without its usual frame but it’s certainly doable.
Off-topic but man look at this cloudhopper community website
Balloon cops
As they are more commonly known the FAA, and their enforcement arm - the USAF
They don’t command them, but they call them in like you call the police.
Fun fact: From time to time, a pilot forgets to change frequency when entering a new area. This means the plane looks like it is not communicating. This is the most common reason why jets are sent to intercept an airliner. Of course, I would pay to see a recording of the pilots as they see the jet in front of them and realize they messed up.
Why would they send jets before trying different frequencies?
Seems like a waste of resources and too rapid of an escalation imo
You need a license. And yes the balloon cops (FAA) will be all over your ass in no time.
How come I don’t see any high-speed balloon chases then?
But my BIL had to get a license to fly his drone and needs to get approval from the FAA to go over like 100ft at my MILs house because it’s “so close” (like 3 miles in a straight line) to the airport.
How come I don’t see any high-speed balloon chases then?
That is impeded by laws higher than your country’s.
Depends on if you’re a Chinese balloon… in which case… have fun eating AIM-9X Sidewinder missiles fired from a U.S. Air Force F-22 Raptor lol.
