Tom Henry is a former bush pilot and Justice of the Peace. Since the 1950s, he has flown small planes, including a Cessna 172 and a Cessna 180. For years, he'd fly American hunters up to the lodges where they'd hunt for bear and wolves.

During one of his supply runs, he and a fellow pilot by the name of Russ McKay were about to come in for a landing on runway 25 at the Thunder bay airport when they saw a large blimp-shaped object hovering in front of them, blocking their flightpath to the landing strip. The Air Traffic controller said they had momentarily picked up a radar contact near their vicinity, but it soon disappeared.
