In a climate of heightened tensions, China was caught sending a spy balloon over the United States, causing an F-22 to take off and a missile to be fired to destroy the balloon. China defends itself from having spied on the United States, claiming that it was a weather balloon. This gives us the opportunity to look at both, a spy balloon or weather balloon?

Discover the details about spy balloons and weather balloons. Understand how they are used for surveillance and weather data collection, as well as their advantages and disadvantages compared to other means of surveillance.

A spy balloon or weather balloon

A weather balloon is a balloon that is used to collect weather data such as temperature, humidity, air pressure and wind. These balloons are usually made of latex or polyethylene, and are equipped with a gondola that contains the instruments needed to collect the data. Weather balloons are widely used by meteorologists to forecast future weather conditions.

A spy balloon, on the other hand, is a balloon that is used to collect covert information. Spy balloons can be used to observe sensitive areas, track the movements of enemy military forces, or collect strategic information. Spy balloons can be equipped with cameras, microphones, sensors and other instruments to collect the desired information.

Distinguishing between spy balloons and weather balloons can be difficult, as spy balloons can often be designed to look like weather balloons. However, spy balloons can be smaller and more elaborate than standard weather balloons. Spy balloons may also be able to fly at higher altitudes and collect information for longer periods of time. Experts can use tools such as radar, motion sensors and infrared cameras to identify spy balloons.

The use of balloons for spying

Balloons are used for spying because they offer a relatively inexpensive and unobtrusive way to monitor areas from a distance. Balloons can fly at high altitudes and are equipped with cameras and other surveillance instruments to collect information on the ground. Balloons can also stay in the air for longer periods of time than drones, allowing them to cover a larger area.

Satellites are also used for surveillance and spying, but they are generally more expensive and complex to deploy than balloons. Satellites also provide wider coverage and can provide more detailed imagery due to their position in orbit. However, satellites are also more visible and can be spotted more easily, which can make their use for covert missions more difficult.

The choice between using balloons or satellites depends on the mission and the resources available. Balloons can be a practical solution for some short-range surveillance tasks, while satellites are better suited for larger-scale, more complex missions.

Long-distance flights

Flying ever greater distances has always been the goal of balloonists. The first successful air crossing of the English Channel took place on January 7, 1785, in a gas balloon piloted by French balloonist Jean-Pierre Blanchard and American balloonist John Jeffries. Another first long-distance flight was made by the English balloonist Charles Green, accompanied by the Irish musician Thomas (“Monck”) Mason, in the Great Balloon of Nassau in November 1836. Taking off from London, they covered about 750 km (480 miles) in 18 hours to land in the Duchy of Nassau (now in Germany). Paul (“Ed”) Yost and Donald Piccard made the first hot air balloon crossing of the English Channel in 1963.

The New York Sun newspaper reported on April 13, 1844 that Monck Mason had made the first transatlantic balloon crossing, but this report turned out to be a hoax by Edgar Allan Poe. The actual first transatlantic balloon crossing took place in 1978 aboard the Double Eagle II, a helium-filled balloon built by Yost, with piloting duties shared by three New Mexico businessmen, Ben L. Abruzzo, Maxie Anderson and Larry M. Newman. The first trans-Pacific balloon flight was made in 1981 by Americans Abruzzo, Newman, Ron Clark and Rocky Aoki in the helium-filled Double Eagle V.

In 1987, British entrepreneur Richard Branson and Swedish aeronaut Per Lindstrand, aboard the Virgin Atlantic Flyer, made the first transatlantic flight in a hot air balloon. And in 1991, aboard the Otsuka Flyer, they made the first transpacific hot air balloon flight. In 1984, American aviator Joseph W. Kittinger, aboard Rosie O’Grady’s helium-filled peace balloon, made the first solo transatlantic balloon flight. In 1995, American adventurer Steve Fossett, aboard the helium-inflated Solo Challenger, made the first trans-Pacific balloon flight.

Several round-the-world balloon flights were attempted with different systems, but success was finally achieved in 1999 by Swiss balloonist Bertrand Piccard (son of Jacques Piccard, grandson of Auguste Piccard and great-cousin of Donald Piccard) and British balloonist Brian Jones in a hot-air and helium balloon suit, the Breitling Orbiter III, with a pressurized cabin. The first solo round-the-world balloon flight was made by Fossett in a hot air and helium balloon suit, the Bud Light Spirit of Freedom, in 2002.

The success of the Breitling depended on several independent factors. Balloon design, cabin design, and meteorological technique were all unique and individually critical. Although other techniques could be used, all major long-distance manned flights have used the jet stream. This limits the altitude, trajectory, and season for a successful attempt to the winter months in mid-latitudes at altitudes of about 6,000 to 10,000 meters (about 20,000 to 35,000 feet).

To navigate a balloon on a long distance flight, the pilot must take advantage of the weather conditions. Close attention to altitude, rate of climb, and global positioning instruments is essential to follow the minute-by-minute advice of the weather coaches on the ground. Information, including complete weather maps, can be communicated through wireless Internet connections via e-mail. For an intercontinental flight, which may last several days, re-evaluation of computer-generated weather forecasts is important; for a global circumnavigation, it is essential.

For a successful global voyage, only general weather conditions can be chosen. It is impossible to calculate the weather conditions two or three weeks in advance in all places of the world. The general conditions and the immediate forecast determine the decision to launch the balloon. Once the balloon is airborne and underway, the weather model must be constantly updated and the balloon accurately steered to take advantage of changing conditions. While 19th century aeronauts had balloons that could theoretically cross the Atlantic, all attempts failed because they lacked the meteorology to make accurate forecasts and the means to communicate the forecasts to the balloonist.

Weather balloon flight altitudes typically range from 15 to 20 kilometers, with extremely low temperatures and very low air pressure at these altitudes. Weather balloons are designed to fly in the upper atmosphere and the information collected is used to forecast future weather conditions.

Spy balloon flight altitudes depend on many factors, such as the mission, weather conditions, and the size and design of the balloon. Spy balloons can fly at higher altitudes than weather balloons, reaching altitudes of up to 25+ kilometers. Spy balloons can also be equipped with propulsion systems to keep them flying at stable altitudes for an extended period of time.

In terms of balloon altitude records, the current record for the highest altitude reached by a balloon is held by a stratospheric balloon called “StratEx”. This balloon reached an altitude of over 39 kilometers in 2014, setting a new world record.
