evidence: The alleged Chinese spy balloon that was shot down after traversing the continental U.S. has raised questions about whether other airships like it have floated into other countries’ airspace in the past. [...] Rep. Michael Waltz (R-Fla.), a member of the House Armed Services Committee, told the Washington Post that lawmakers and military officials spoke on Saturday to discuss previous instances of similar surveillance balloons in the U.S. During the Trump Administration, a Chinese spy balloon reportedly made its way to Texas and Florida, military officials said Sunday. Another such balloon made it to Guam. One crashed off the coast of Hawaii four months ago, Fox News reported. [...] In the most recent incident in the U.S., a Chinese spy balloon was spotted about 60,000 feet over Billings, Montana on Feb. 1. It passed through Alaska and Canada, as well as parts of Idaho and Missouri, before the military shot it down above the Atlantic Ocean off the South Carolina coast.
