TRINDADE.

Aboard was Almiro Baraúna, an underwater photographer hired to document the expedition. As the ship's officers and crew watched, an oblate, Saturn-shaped object passed over the island peak, paused, and accelerated away. Baraúna ran for his camera and captured four photographs of the object during its brief visibility.

The negatives were developed in a lab on the ship and Baraúna initially showed them to a small group of officers including Captain José Santos Saldanha da Gama. Two crewmen who had not seen the object reportedly identified it in the developed photographs based on the others' descriptions. The Brazilian Navy investigated, including interviews with witnesses, technical examination of the negatives by the Aeronautics Department, and consultation with photographic experts. The Navy could not determine a conventional cause and forwarded the report up the chain.

Brazilian president Juscelino Kubitschek released the photographs publicly in February 1958 and personally endorsed them as showing a real, unidentified object. They became among the most widely reproduced UFO images of the 20th century. Decades later, in 2010, photographer and UFO historian Kevin Randle and others investigated alleged confessions attributed to Baraúna of having faked the photographs. The provenance of the alleged confessions has been disputed by Baraúna's family.

The Trindade Island photographs remain a contested but historically central image set. They are notable for being officially released by a sitting head of state and supported by sworn naval testimony — circumstances rare in any UFO case worldwide. Whether the photographs are authentic, faked, or some combination of staged elements with genuine sighting reports remains a matter of ongoing debate.
