i am a communications engineer & was working at remote radio site on mount callahan. we were driving down from mount callahan at 8pm, we entered a clearing and saw a bright light in the sky just out in front of us about 1000 yards. it was just sitting there about 30 degrees up in the air. we stopped the truck and got out to watch it. in an instant it became a very large triangle with 2 lights in each corner. the object appeared to rotate slowly for about a minute. the body blotted out the stars. then it suddenly became a massive rectangle with about 30 lights around the parameter. it did not move or make any sound for about a minute. then it just was gone as if turning off a light. about 5 seconds later we could hear a very loud rushing air sound just above us, but we could not see anything above us, just stars. the sound got louder, then slowly as if flying away, got softer & softer until silence. this lasted about 20 seconds. this was an extremely remote commutations site, our trucks were the only lights for 20 square miles. i felt that it had been watching us and then just appeared directly in front of us, did it's little show and left.
