These photos show the prototype installation of TCTO 1F-106-674, dated 3/16/62, and was designed to provide Nuclear Flash and Thermal Radiation Protection to the pilot and was to have been installed as part of the Dartboard Modification. To make a long story short, it was decided not to install the modification. With the fully pressurized "space suit" and supersonic ejection seat filling up the cockpit, the modification was deemed impractical and almost impossible to use.
