Exopolitics Institute author and researcher Michael Salla says “As the photos and video make clear, there is unmistakable evidence of UFOs of an artificial design that have been photographed by NASA’s earth orbiting spacecraft. The UFO does not correspond to any known terrestrial spacecraft and appears to be alien in design. Nothing is known of the occupants, but Clark McClelland a former NASA employee who completed training as a Spacecraft Operator may have the answer.

During a 34 year career working as a NASA contractor/employee, McClelland was responsible for ensuring the safety of numerous NASA missions including Mercury spaceflights, Apollo missions, the International Space Station and the Space Shuttle. In a statement released on his website on July 29, 2008, McClelland revealed that he witnessed an eight to nine foot tall extraterrestrial in association with a Space Shuttle mission he was monitoring from the Kennedy Space Center.

McClelland  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!

Furthermore, McClelland wrote that he was not the only NASA official who witnessed the incident: “A friend of mine later contacted me and said that this person had also observed an 8 to 9 foot tall ET INSIDE the SPACE SHUTTLE CREW COMPARTMENT! Yes, inside OUR Shuttle! BOTH missions were DoD (Pentagon) TOP SECRET (TS) encounters!’
