Enormous metallic disc in Alaska sky, 1949

Encounter reported from the NUFORC.ORG website:

"I was born and raised in the Territory of Alaska and in 1949 I was a student at the University of Alaska at Fairbanks. During the summer of 1949 I worked as a transit man on a survey line for the Civil Aeronautics Administration which was beginning the development of the Fairbanks International Airport.

On a clear day in July, in a sky void of sound or activity, there appeared an enormous metallic saucer-shaped object directly above my line of sight, but at a great distance from us.

I shouted to my two chainmen and pointed to the object which was approaching rapidly until it appeared directly above us, but still at an altitude higher than any aircraft I had ever observed. Its size was enormous. I imagined it would cover several city blocks in size.

It was visible for about a couple of minutes before it made a sharp right angle turn and climbed out of sight. Only one of the chainmen saw the object. The time of the sighting was about eleven o’clock in the morning.

At noon it was time for our break and we headed back to the survey station where the sighting was discussed with others.

By the end of the day our story had reached the military at Ladd Field and when we arrived back at the station we were approached by an Army officer who interrogated us separately regarding the sighting. When I was asked how high it was I responded that it was at least at an altitude of 30,000 feet. The officer asked why I would choose that altitude and I said it was because I knew of no aircraft that could reach that altitude.

I am aware that this was a very early sighting but understand that your organization is nevertheless interested in recording all reliable sightings, and since I am now in my eighties there is no time like the present to report it. "

Location is an approximation
