Thy are held up by gas that is lighter than air. The hgher you go, the less dense air gets and therefore the less the difference between the gas being used to hold the balloon aloft and the air outside.
They can therefore only go so high.
Also, most balloons are not pressurised therefore the people fying in them would pass out for lack of oxygen if they went much above 10,000feet
Aerostat radar is a low-level surveillance system that uses aerostats (moored balloons) as radar platforms.
Most small airplanes are not air tight (or even completely encased) because thy do not need pressurization. Commercial planes fly at altitudes where there is not enough oxygen to sustain life, requiring pressurization.
No, balloons are not always made from rubber. While many traditional balloons are made from natural or synthetic rubber, there are also balloons made from materials like latex, Mylar (a type of polyester), and other plastics. Each material offers different properties, such as durability and the ability to hold helium. Therefore, the composition of balloons can vary widely depending on their intended use.
BALLOONS
They did, but sometimes the planes would fly very low so that the radars could not detect them.

Weather balloons fly in the stratosphere layer of the atmosphere, typically reaching altitudes of around 20-30 km. This layer is above the troposphere where most weather occurs, allowing weather balloons to collect data on temperature, humidity, and atmospheric pressure.
They fly at low altitudes because if you fly too high, the balloon may pop. A2: Above seems unlikely, as the balloon is open at its lower end. Mainly I think because they are generally used for passenger viewing flights and the general public would not have the clothing for high altitudes as well as not wanting to be very high since the purpose of the flight is to view the terrain below. The balloon works by making the air inside hotter and less dense than the surrounding air, so as it rises it needs to use more fuel to achieve this as the surrounding air gets less dense. There must be an effective max height for hot air balloons but I don't know what the record is.
Better fuel economy. The air is thinner at higher altitudes.
to fly eat balloons as kerby you well unlock the power to float
Yes, it is possible to fly with balloons by using a hot air balloon or helium balloons, but flying with small party balloons is not feasible for human transportation.
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
Hot air balloons travel at low altitudes because they rely on the differences in air temperature at various altitudes to navigate. By staying closer to the ground, hot air balloon pilots can easily adjust their altitude by using the burner to heat the air inside the balloon to ascend or allowing it to cool to descend. Additionally, flying at low altitudes provides better visibility and a more immersive experience for passengers.
After weather balloons are released into the atmosphere, they ascend to high altitudes, collecting data on temperature, humidity, and pressure. Eventually, the balloons burst due to low air pressure, and a parachute deploys to slow their descent. The instruments attached to the balloon are then retrieved for analysis of the gathered data.
You can float using the balloons, but not fly.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
