Radar reveals impossible Concorde reappearance

Air traffic controllers Horton and Sheard witness the unthinkable as their radar screen displays the reappearance of Concorde Golf Alpha Charlie where no flight should exist. The aircraft materializes without signal, without flight plan, defying every principle of air traffic control and physics.
