Several conceptual layouts for cockpits for a supersonic nuclear powered seaplane from Convair, drawing in 1956. To protect the crew from radiation, the cockpit was surrounded by a massive lead-lined shield, and only a relatively small leaded-glass transparency was provided for the pilot to see through. To minimize what was necessarily an enormous mass, the shield and transparency were flat and un-aerodynamic; the aircraft needed aerodynamic fairings around them. Easy enough except that the pilot needed to be able to see through those as well. So very large secondary windscreens were needed. Several possible layouts were examined and are shown below.
