Strange goings-on are happening in skies above North America. This month, US fighter jets have shot down four UFOs (Unidentified Flying Objects) in US and Canadian airspace. Officials said objects were balloons that were causing danger to airplanes. They were flying at altitude of around 40,000 feet (12,200 metres). The White House said yesterday that there were no signs objects were linked to alien life. National Security Council spokesperson John Kirby said: "I don't think American people need to worry about aliens with respect to these crafts." Earlier in week, US official said aliens could not be counted out as possible explanation for balloons.
balloon saga has created tit-for-tat exchanges between USA and China. US officials suspect the balloons were being used for spying. However, they have no proof of this. Rescue teams have gathered debris from balloons off the US coast. Experts are currently looking at electronics they have found. China said balloons were for tracking weather patterns. It has denied they were spy balloons. Beijing has claimed that US high-altitude balloons have flown in China's airspace without permission more than ten times in past year. The White House said this was untrue. balloon shooting in early February resulted in US Secretary of State Antony Blinken cancelling visit to China.
