There was also speculation that it was all part of Google's Project Loon, which uses large balloons to provide internet service in remote areas.
But Google reportedly shot that theory down.
Turns out, the most likely culprit seems to be a shadowy Pentagon body called the Defense Advanced Research Projects Agency (DARPA), which tweeted that it had launched balloons as part of a flight test that began Monday.
Last night, DARPA launched 3 balloons from Cumberland, Maryland, in a flight test for the Adaptable Lighter Than Air prgm. Over next few days, ALTA will demonstrate capability for wind-borne navigation of a lighter-than-air vehicle over extended ranges. https://t.co/Og8dWCvszc pic.twitter.com/NjUB6Got94— DARPA (@DARPA) June 18, 2019
Flight radar reportedly shows two of the balloons nearly 1,000 miles from where they started, passing over, yes, Kansas City.
