The first known use of this technique for military purposes For which there is evidence of dates from 1794during the French Revolutionary Wars. However, these devices have come a long way since then.

What materials are they made of?

according to Canadian Space Agency (ACS) These balloons are usually of a Very thin plasticare filled with it heliumas with traditional hot air balloons, and you have a basket at the bottom in which you can hold different types of tools as well as a series of solar panels to power the device.

How big are they?

Based on the statements of A.A A senior American official Already retired, these balloons can stretch in the form of an inverted teardrop until it reaches a height similar to that ofThree buses». However, the exact dimensions of the device that entered US soil are not known, although the Senior defense official of the Joe Biden administration admitted that “it was big enough to cause damage in the debris field if we were going to drop it over some area.”

What technology do they use?

These devices are usually equipped with a series of baskets It is located in the lower part of the globe, which can carry a scientific, astronomical or weather forecastIn addition to camerasGPS radars and sensors communication equipment Even swarms of Drones, they point out from the BBC.
