Four years from now, Concorde is scheduled to enter airline service, carrying passengers at the speed of a bullet through an atmosphere too thin to support human life.
How can we be sure that it will be as safe as - or safer than - any of today's subsonic aircraft?
This programme shows the work that must be done now to get Concorde into Service.
Engineers who are building and testing Concorde, and the men who will fly it, are introduced by Brian Widlake and Peter Stone.
