Just joined this site. I was there in 1980 also. I was a 19 year old former PR from the nearby NADC Warminster Naval Air Warfare Center. I served there for 4 yrs and got out in march 1979. I stayed in the area and tried out the local job market until August 1980, when I reenlisted. I was a Naval Aviation nut and frequently volunteered to host tours for boy and cub scouts and local media and civilian contractors. Warminster was only a 15 minute bicycle ride from Willow Grove NAS. I tried to catch every air show I could and enjoyed every one. On July 4, 1980 I rode my bicycle to NAS Willow Grove for the show. I saw the S-3 involved in the accident and was no more than 50 yards from it when it happened. It was HOT, it was HUMID. I rode past the S-3 and and noticed the stairs and the people lined up for a cockpit view. The stairs were on the starboard side of the S-3. There were people under the port side of the S-3 who were sheltering from the heat under the shade of the wing. There was a big boom and I instantly pivoted back to the sound. I saw a 28 foot flat parachute canopy floating in the breeze above the S-3. My first thought was where is that seat! I reached the S-3 and I saw a young woman under the port wing in a lawn chair with a stunned look on her face. I spun around and saw something on the tarmac (ramp). I didn't see him land but I was the first person to get to him. I will never forget that sight. It was soo surreal. I don't want to get graphic on my first post but I can give you graphic details of what I saw on that day.
