RB-57D Canberra – Warbird Wednesday Episode #173

Welcome to Warbird Wednesday! Today we are continuing down reconnaissance row again and looking at the RB-57D Canberra, an aircraft that led to the development of the U2. The Canberra had a unique design with a very large wing that held fuel inside and used glue instead of rivets to be held together. The wings were delicate and could be punctured if a tool had been dropped on them while working on the aircraft. These factors required that the wings have a 500-hour lifespan.
