Peru's OIFAA and the La Joya interception

The office. The Peruvian Air Force (FAP) runs an office for anomalous aerial phenomena. The press calls it the DIFAA (Departamento de Investigación de Fenómenos Aéreos Anómalos). The FAP's own state news agency, Andina, calls it the OIFAA (Oficina de Investigación del Fenómeno Aéreo Anómalo). - It was created in 2001. Its first documented case was Chulucanas, Piura, 13 October 2001: reportedly eight red-orange spheres watched by hundreds of people for over five hours. The chief investigator then was Anthony Choy. - It went dormant around 2005-2008. Sources differ, and the reasons were "administrative problems". - In October 2013 the FAP's Dirección de Intereses Aeroespaciales (DINAE), headed by Col. Julio Vucetich, announced it would reopen. It was to bring together Air Force personnel with sociologists, archaeologists, astronomers and meteorologists, and to take reports from the public. - It has been led since October 2013 by Cmdr. (ret.) Julio César Chamorro Flores. He is a former La Joya radar operator trained in the USSR. - I found no published OIFAA case file or archive. The UFO Transparency mirror has no Peruvian files. The case. In 2013, OIFAA's head pointed to La Joya as the reference case. On the morning of 11 April 1980, Lt. Óscar Santa María Huertas was scrambled in a Sukhoi Su-22 from La Joya to intercept an object over the base. The base suspected an espionage balloon. He fired about sixty 30 mm rounds at it with no visible effect. He then chased it for about 22 minutes up to about 63,000 ft, and broke off short of fuel. The incident was reported by the US defence attaché in a June 1980 DoD message titled "UFO Sighted in Peru". That message is widely cited, and Santa María submitted a copy of it at the 2013 Citizen Hearing. It states the object's origin as unknown. I could not obtain or read that message, and the date (April or May 1980) and other details vary between accounts. So this is graded sourced, not record.
