Question: Operation Hedge-hop was a military plan developed during the Korean War, a lack of UN supplies forced American forces to use the Lockheed P-80 Shooting Star was the first jet fighter used operationally, by which organization?
Context: The McDonnell FH Phantom was a twin-engined jet fighter aircraft designed and first flown during World War II for the United States Navy.  The Phantom was the first purely jet-powered aircraft to land on an American aircraft carrier and the first jet deployed by the United States Marine Corps.  Although with the end of the war, only 62 FH-1s were built, it helped prove the viability of carrier-based jet fighters.  As McDonnell's first successful fighter, leading to the development of the follow-on F2H Banshee, which was one of the two most important naval jet fighters of the Korean War, it would also establish McDonnell as an important supplier of Navy aircraft.  When McDonnell chose to bring the name back with the Mach 2–class McDonnell Douglas F-4 Phantom II, it launched what would become the most versatile and widely used western combat aircraft of the Vietnam War era, adopted by the USAF and the US Navy. Willis Moore Hawkins (December 1, 1913 – September 28, 2004) was an aeronautical engineer for Lockheed for more than fifty years.  He was hired in 1937, immediately after receiving his bachelor's degree in aeronautical engineering from the University of Michigan.  Prior to that, he was in the first graduating class of The Leelanau School, a boarding school in Glen Arbor, Michigan.  He contributed to the designs of a number of historic Lockheed aircraft, including the Constellation, P-80 Shooting Star, XF-90, F-94 Starfire, and F-104 Starfighter.  During World War II, he was part of the group of Lockheed designers who designed the first American attempt at a jet plane, the Lockheed L-133. The RAM Plan, also known as Operation RAM, Brana Plan, or Rampart-91, was a military plan developed over the course of 1990 and finalized in Belgrade, Serbia during a military strategy meeting in August 1991 by a group of senior Serb officers of the Yugoslav People's Army (JNA) and experts from the JNA's Psychological Operations Department.  Its purpose was organizing Serbs outside Serbia, consolidating control of the Serbian Democratic Parties (SDS), and preparing arms and ammunition in an effort of establishing a country where "all Serbs with their territories would live together in the same state."  A separate group of undercover operatives and military officers was charged with the implementation of the plan.  These people then undertook numerous actions during the Yugoslav Wars that were later described as ethnic cleansing and genocide. The Gloster Meteor is a twin-engined jet fighter, the first jet aircraft to serve with the RAF and the only Allied jet aircraft to reach combat in World War II.  Almost 4,000 were produced, mostly in service with the RAF between 1944 and 1965.  Meteors also served with the Royal Australian Air Force (RAAF), whose aircraft saw action in the Korean War; other users included the Argentinian, Brazilian, Belgian, Danish, Dutch, Ecuadorian, French and Israeli air forces.  Many are preserved but only five are airworthy. Colonel Daniel J. Miller was born in Stony Point, New York.  He enlisted in the United States Army Air Forces during World War II and served in the 826th Bombardment Squadron as a navigator in a B-24 Liberator.  During the Korean War, he flew various aircraft, including the F-86 Sabre jet fighter.  In the late Korean War and throughout the Vietnam War, he flew helicopter rescue missions.  He was awarded the Silver Star during the Korean War in the 3rd Rescue Squadron.  He braved heavy enemy fire in low visibility to rescue USMC Major Frank H. Presley.  Immediately after rescuing Presley, his P-51 fighter escort was shot down, and he once again braved the fire to attempt to rescue USAF Captain Willis R. Brown, but Brown had failed to eject and had perished.  In addition, he was also awarded the Cheney Award for a rescue in February 1951, when he rescued six wounded soldiers behind enemy lines in three attempts despite snow and enemy fire.  During Vietnam, he flew rescue missions and commanded a light reconnaissance squadron, the 19th Tactical Air Support Squadron. The Lockheed T-33 Shooting Star (or T-Bird) is an American jet trainer aircraft.  It was produced by Lockheed and made its first flight in 1948 piloted by Tony LeVier.  The T-33 was developed from the Lockheed P-80/F-80 starting as TP-80C/TF-80C in development, then designated T-33A.  It was used by the U.S. Navy initially as TO-2 then TV-2, and after 1962, T-33B.  The last operator of the T-33, the Bolivian Air Force, retired the type in July 2017, after 44 years of service. Operation Hedge-hop was a military plan developed during the Korean War.  A lack of UN supplies forced American forces to use P-80 high-altitude jets as low altitude strike bombers, beginning in late 1950.  The innovation paid off. Plan Patriota (In English, "Patriot Plan") is military plan developed by the Government of Colombia with the financial support of the Government of the United States in an effort to uproot the guerrilla groups in Colombia, more specifically the Revolutionary Armed Forces of Colombia (FARC-EP) and the National Liberation Army (ELN).  The plan is part of the government of President Álvaro Uribe's democratic security doctrine.  The plan is also intended to get military presence to the most remote areas of Colombia, where the guerrilla had enclaves, and enable the introduction of social programs.  Some analysts consider the plan to be a sort of second phase of Plan Colombia. The Lockheed P-80 Shooting Star was the first jet fighter used operationally by the United States Army Air Forces (USAAF).  Designed and built by Lockheed in 1943 and delivered just 143 days from the start of the design process, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II.  Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80. The Lockheed L-133 was an exotic design started in 1939 which was proposed to be the first jet fighter of the United States Army Air Forces (USAAF) during World War II.  The radical design was to be powered by two axial-flow turbojets with an unusual blended wing-body canard design capable of 612 mph (985 km/h) in level flight.  The USAAF passed on the 1942 proposal, but the effort speeded the development of the USAAF's first successful operational jet fighter, the P-80 Shooting Star which did see limited service near the end of war.  The P-80 was a less radical design with a single British-based Allison J33 engine, with a conventional tail, but it retained a wing which was the same shape as the outer wing sections of the P-38 Lightning.
