April 23, 2007-The images correspond to photos taken at Sierra de la Ventana, Province of Buenos Aires, during an investigation carried out by CIUFOS-LAPAMPA and in which it is possible to observe the presence of "chance UFOs".

The photos were taken from the base as part of an effort to capture on film the hole or space that gives this mountain range its name, and from its crest, in order to show access to the site.

The presence of UFOs was detected during the processing of the photographic material. A Vivitar N3000 camera was the instrument employed, and 100-200 ASA film.
