GASCAP was an acronym for Graphics Application Software for Cruise missile and Aircraft Planning. It was a 3D application used to plan B-52 and AGM-86 cruise missile missions in support of the SIOP each year. It was the first application that I worked on. Below the GASCAP screen tries to show what the sign on screen looked like on an IBM 3270 terminal. The 3D window emulates an Adage 4370.
