The Guardian: UFOs over US and China could be ‘heavenly debris’

Around 2,000 hot air balloons are launched into the sky every day around the world to monitor everything from the weather to specific phenomena in space. However, the purpose and origin of the flying objects shot down over Alaska, Canada and Lake Huron is still shrouded in mystery.
Most likely, some of them may be the so-called “heavenly debris”. objects, related quite a few fall into this category, said Harvard-Smithsonian Center for Astrophysics astronomer David Martin. Usually they fly at an altitude of eight to 40 km. As a rule, the balls eventually fall to the Earth, but some part continues to drift in the stratosphere.
Astrophysicist and astronomer from the Australian National University Brad Tucker explained that using balloons for scientific observations is much cheaper and more rational. He found it difficult to say how many flying objects could be in the sky.
“It can be anything from hot air balloons to high-altitude drones. Or debris caught in the wind. Like plastic bags and party balloons,” Tucker said.
According to the US National Weather Service, 1,800 weather balloons are launched every day worldwide, 92 of them in the US. Everyone has an instrument for measuring pressure, temperature and relative humidity.
Private companies launch thousands of balloons every year. Until 2021, Google launched hundreds of tennis court-sized homing balloons into the sky to bring the Internet to rural and remote areas.
