Richard Hammond's Engineering Connections

Richard Hammond stands atop of the Wembley roof, in front of its record-breaking arch to discover the Engineering Connections behind the new high-tech home of English football. Richard reveals how the architects and engineers, under pressure to maintain Wembley's iconic status as a world-class sporting and music venue, drew inspiration from a rock climbing knot, the first glider to carry a man, a high powered medieval crossbow, stealth aircraft technology and Archimedes' buoyancy theory that surfaced over two thousand years ago.
