Pentagon officials said they did not believe the balloon had surveillance or intelligence-gathering capabilities above and beyond Chinese spy satellites in low earth orbit, In the past, the US has simply allowed balloons like this to waft away, without taking any action or publicizing their presence over the US, the sources said. It is also not the first time a surveillance balloon has appeared over the United States. The US official said there were similar incidents with suspected Chinese surveillance balloons over Hawaii and Guam in recent years.
