He wrote:
"I, Clark C. McClelland, former ScO [Spacecraft Operator], Space Shuttle Fleet, personally observed an 8 to 9 foot tall ET on his 27 inch video monitors while on duty in the Kennedy Space Center, Launch Control Center (LCC). The ET was standing upright in the Space Shuttle Payload Bay having a discussion with TWO tethered US NASA Astronauts! I also observed on my monitors, the spacecraft of the ET as it was in a stabilized, safe orbit to the rear of the Space Shuttle main engine pods. I observed this incident for about one minute and seven seconds. Plenty of time to memorize all that I was observing. IT WAS AN ET and Alien Star Ship!"
