White light object seen on Kodial Island in the mid 70sI was stationed on the USCG base during this time. Before this sighting I was in a building the base command had given me to set up a Ham Radio station. I was on the air late into the morning till around 2am or so.I had been transmitting and talking to another ham radio station. During the end of the converstion with the other station I noticed a large drop in the power line voltage. It dropped to the point that my ratio equipment would not functin correctly. I then shut down my station and left the building to go back to the building where I lived and go to bed. As I left the building with where my radio station was, I noticed a bight, perfectly round shaped light hovering about 100 feed above the ground close to the runway that was on the Coast Guard base. This distance from me was maybe 300 yards.As I watched the object it moved up to an altitude of about 500 ft and down several times. I continued wo watch it. It then hovered perfectly still and then began moving in strange angles back and forth. It then climbed up to several hundred feet, and suddenly shot away into space like a flash. The acelleration was very rapid and the movement was very erratic....It was gone, I mean gone. I stood there completely stunned for several minutes, shaking in awe. I then went back to the barracks and woke up one of my buddies to tell him the story. At first I thought it might be a light from a hellicpoter, but there was NO sound, and the movements were too sharp and erratic to be any normal aircraft. Was this craft attracted to my radio signals in the moments before I came out of the building? Was it attempting to communicate with me by messing with the power? I have wondered about this for years?
