After an immense high-altitude balloon drifted over the United States and was shot down in the end of January, several other mysterious smaller aerial objects were detected in US airspace. According to CSS' Mauro Gilli, this happened because the US air defense network changed filtering functions in its radar to see whether there were other balloons up in the sky that had got undetected. This led to many more 'false alarms', he tells the Tribune.
