Question: What was the codename, in english, of the operation that the Lockheed C-130 Hercules of the 1st Transport group of the 1st Air Brigade was a part of when it was brought down by Montoneros in Operation Gardel?
Context: The Royal Australian Air Force (RAAF) has operated forty-eight Lockheed C-130 Hercules transport aircraft.  The type entered Australian service in December 1958, when No. 36 Squadron accepted the first of twelve C-130As, replacing its venerable Douglas C-47 Dakotas.  The acquisition made Australia the first operator of the Hercules after the United States.  In 1966 the C-130As were joined by twelve C-130Es, which equipped No. 37 Squadron.  The C-130As were replaced by twelve C-130Hs in 1978, and the C-130Es by twelve C-130J Super Hercules in 1999.  No. 37 Squadron became the RAAF's sole Hercules operator in 2006, when No. 36 Squadron transferred its C-130Hs prior to converting to Boeing C-17 Globemaster III heavy transports.  The C-130Hs were retired in November 2012, leaving the C-130J as the only model in Australian service. Operativo Independencia (Spanish for "Operation Independence") was the code-name of the Argentine military operation in the Tucumán Province, started in 1975 to crush the ERP —"Ejército Revolucionario del Pueblo" or "People's Revolutionary Army"—, a Guevarist guerrilla group, which tried to create a Vietnam-style war front in the Tucumán Province, in northwestern Argentina.  It was the first large-scale military operation of the Dirty War. The Lockheed C-130 Hercules is a four-engine turboprop military transport aircraft designed and built originally by Lockheed (now Lockheed Martin).  Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, medevac, and cargo transport aircraft.  The versatile airframe has found uses in a variety of other roles, including as a gunship (AC-130), for airborne assault, search and rescue, scientific research support, weather reconnaissance, aerial refueling, maritime patrol, and aerial firefighting.  It is now the main tactical airlifter for many military forces worldwide.  Over forty variants and versions of the Hercules, including a civilian one marketed as the Lockheed L-100, operate in more than 60 nations. Lars Oskar Olausson (born 20 May 1927) is a retired Lieutenant Colonel of the Swedish Air Force, who has published an annual volume on the history of the Lockheed C-130 Hercules airlifter currently titled the "Lockheed Hercules Production List 1954-2014", the thirtieth edition having been printed March 2012.  "For each aircraft listed, the Lockheed model number, military designation, owner and serial number are quoted, with additional information in a remarks column, giving such details as delivery dates, earlier or later markings, using squadron and write-off date." The Airbus A400M Atlas is a multi-national, four-engine turboprop military transport aircraft.  It was designed by Airbus Military (now Airbus Defence and Space) as a tactical airlifter with strategic capabilities to replace older transport aircraft, such as the Transall C-160 and the Lockheed C-130 Hercules.  The A400M is positioned, in terms of size, between the C-130 and the C-17; it can carry heavier loads than the C-130, while able to use rough landing strips.  Along with the transport role, the A400M can perform aerial refuelling and medical evacuation when fitted with appropriate equipment. Operation Gardel was the codename given by the Peronist guerrilla organization Montoneros to the downing of a Lockheed C-130 Hercules, belonging to the 1st Transport Group of the 1st Air Brigade, as it took off the old "Teniente General Benjamín Matienzo" International Airport, carrying 114 Gendarmerie personnel as part of the Operativo Independencia. No. 486 Squadron was a maintenance unit of the Royal Australian Air Force (RAAF).  It was formed in August 1946 as part of No. 86 (Transport) Wing, which operated Douglas C-47 Dakotas out of RAAF Station Schofields, New South Wales.  The squadron transferred to RAAF Station Richmond in June 1949.  It relocated again to RAAF Base Canberra in April 1954, before returning to Richmond in August 1958 to commence maintenance of No. 86 Wing's newly delivered Lockheed C-130 Hercules.  The squadron was disbanded between August 1964 and March 1966.  In the 1980s and 1990s, it was responsible for servicing the RAAF's Boeing 707 tanker/transports, as well as the Hercules.  No. 486 Squadron was again disbanded at Richmond in October 1998, and its functions handed over to No. 86 Wing's Hercules squadrons. The Lockheed MC-130 is the basic designation for a family of special mission aircraft operated by the United States Air Force Special Operations Command (AFSOC), a wing of the Air Education and Training Command, and an AFSOC-gained wing of the Air Force Reserve Command.  Based on the Lockheed C-130 Hercules transport, the MC-130s' missions are the infiltration, exfiltration, and resupply of special operations forces, and the air refueling of (primarily) special operations helicopter and tilt-rotor aircraft. The Lockheed Martin C-130J Super Hercules is a four-engine turboprop military transport aircraft.  The C-130J is a comprehensive update of the Lockheed C-130 Hercules, with new engines, flight deck, and other systems.  The Hercules family has the longest continuous production run of any military aircraft in history.  During more than 60 years of service, the family has participated in military, civilian, and humanitarian aid operations.  The Hercules has outlived several planned successor designs, most notably the Advanced Medium STOL Transport contestants.  Fifteen nations have placed orders for a total of 300 C-130Js, of which 250 aircraft have been delivered as of 2012 . Cervia Air Base (ICAO: LIPC) is an air base of the Italian Air Force (Aeronautica Militare).  It is located in northern Italy, approximately 6 km southwest of Cervia, in the province of Ravenna (Emilia-Romagna).  It was the home of the 5th Fighter Wing, which flew leased US Air Force Lockheed Martin F-16 Falcon.  It is also a NATO air base and is visited by other NATO air forces on a routine basis.  After Italy returned the leased F-16 to the US Air Force the 5th Fighter Wing was disbanded and in its place the 1st Special Air Brigade moved to Cervia.  Along with the 1st Special Air Brigade arrived the 15th CSAR Wing - the Italian air force's Combat Search and Rescue wing.
