The Spirit of Knoxville is a high-altitude balloon project run by amateur scientists and University of Tennessee students, with the ultimate goal of successfully sending an unmanned balloon across the Atlantic Ocean. The project is named for Charles Lindbergh's record-breaking Spirit of St. Louis aircraft. As of November 2008, five flights have ...

The presence of the high-altitude balloon comes approximately one year after a high-altitude balloon originating from China drifted over the US, causing national attention and political tension.
VanHerck, meanwhile, warns that the Chinese balloon program remains active and that the U.S. has failed to develop the systems it needs to detect high-altitude spy balloons before they pose a threat.
A balloon the US was tracking across the country has now left US airspace and was likely a “hobby balloon,” NORAD said in a statement Saturday.
Testing radio range is often a large component of these hobbies. Amateur radio is often used with packet radio to communicate at 1200 baud, using the Automatic Packet Reporting System back to the ground station. Smaller packages called micro or pico trackers are also built and run under smaller balloons.
