May 3rd 2013, the President of the United States Barack Obama made a visit to Costa Rica. During the landing of the presidential plane, Air Force 1, at the International Airport, Juan Santamaría , on the edge of the airport there were thousands of people who were waiting for the arrival of U.S. President, ready with the cameras on, to record the event. In one of the many photographs that showed the landing of the plane, you can see a small black dot; a small object that larger, would show the silhouette of a flying saucer. The photograph was released by Mr. Tacsan Leonardo Sanchez, who, through his Facebook profile, has published this photo. We know Aliens are working alongside U.S Government secret services. Are they also guarding Air Force 1 in case of any eventual attack?
