The text calls on military and civilian pilots and air traffic controllers to lodge any experiences with unidentified flying objects with the Aerospace Defense Command in Brasilia along with any material proof by way of photos or video.

That evidence will be catalogued at the air force’s Historic Documentation Center in Rio de Janeiro state, where it will be made available to searchers of extraterrestrial life and other people interested.

The decree was signed by air force chief Juniti Saito.

“Air force command does not have the specialised structure needed to carry out scientific investigations on these aerial phenomena and will only register the events,” the air force said in a statement sent to the newspaper O Dia.

A military air controller in Rio told the daily that respectable witnesses have previously recounted experiences with UFOs.
