The Roswell incident was a balloon, but it's highly unlikely that it was a fire balloon. Most contemporary analysis points to the Roswell incident being caused by one of the Project Mogul balloons [1]. Project Mogul was a top-secret (at the time) project to detect Soviet atomic bomb tests by listening for their shock waves with very sensitive microphones. These microphones were mounted on large hexagonal discs, which, when viewed by an untrained eye, looked like a flying craft of some sort.
