September 4, 1971, an aircraft of the Costa Rican Geographic Institute was photographing the Arenal region for making maps. Not until 4 years later when the negatives were needed to build a water dam is what they found an anomaly. It is one of the best documented #UFO 
ever.
ever.
The case is known as the Lake Cote UFO. Lago de Cote
The camera was set to take pictures automatically every 20 seconds or so. It was a special R-M-K 15/23 camera with b/w film ASA 80, with an 8Ă—8 negative printed on Kodak Safety aerial film, type 3665.

The camera lens have 4 micron distortion threshold. It works automatically taking pictures every 13 seconds. A flight route was set to follow to take at least 2 pictures 3 secs apart of the area to compare them with a Stereoscope to then create a detailed image.
One shot taken at 10,000 feet altitude, frame 300, showed mountains around Cote Lake in Guanacaste Province, 25 miles south of Nicaragua. A disc-like object appeared clearly on the lower half of the lake.

The photo is considered unique and of great scientific value. Drs. Richard Haines & Jacques Vallee listed a number of reasons why in their first study of Cote, published in the Journal of Scientific Exploration in 1989:
“(1) it was taken by a high-quality professional camera

2- The camera was looking down, which implies a maximum distance, hence a maximum size for the object
3- the disc was seen against a reasonably uniform dark background of a body of water; and
4 - the image was large, in focus and provided significant detail.

In 1979, Ricardo Vilchez (right), one of the project team members, sent the photograph to an organization in the United States called Ground Saucer Watch (GSW) which analyzes these types of cases. GSW determined that the image was true and unadulterated, reported CRHoy.
A senior Lockheed analyst raised the objection that the disc may be “a pressure mark” on the film, which was disproven when the Geographic Institute loaned the original negative for further analysis. “The image was smooth as glass so it set to rest that argument,” said Dr. Haines
