RCAF Western Air Command: Western Air Command was the part of the Royal Canadian Air Force's Home War Establishment responsible for air operations on the Pacific coast of Canada during the Second World War.  When Canada declared war against Germany in September 1939 the command consisted of only five squadrons.  Four of them equipped with obsolete aircraft including a bomber squadron with aircraft from the Great War and there were no fighter aircraft at all for its only fighter squadron (113 Fighter Squadron was thus disbanded).  With the Japanese threat after Pearl Harbor it grew rapidly and played a critical role in fighter and anti-submarine operations in Canadian and American waters during the Aleutian Islands Campaign.  It was there that Squadron Leader K.A. Boomer of No. 111 Squadron shot down a Rufe fighter, the RCAF's only kill in the Pacific Theatre.  On 7 July 1942 a Bristol Bolingbroke pressed home an attack on the Japanese Submarine Ro 32 the pilot F/Sgt.  P.M.G. Thomas of No. 115 Squadron RCAF then led American Destroyers to sink the damaged submarine.  By January 1943 Western Air Command had expanded to include many bomber, fighter and operational units under its control.  By the end of the war the command would involve some twenty squadrons when the last units to join were added in 1943.  These were the 163 Army Cooperation Squadron in March flying Bristol Bolingbrokes and Hawker Hurricanes, in May the 160 Bomber-Reconnaissance Squadron was added flying Cansos from Sea Island BC (before moving to Yarmouth NS in July) and the 166 Communication Squadron formed in September flying various types.  In addition to the new squadrons, new aircraft types came on line replacing the command's remaining Supermarine Stranraers and Blackburn Sharks with Canso's and the Bolingbrokes and Beauforts with the Lockheed Ventura.  Countless training missions and operational patrols bolstered the air activity over the coastal areas but there was not much action until RCAF Western Command was on the look out for General Kusaba's Fire Balloons that the Japanese called the Fūsen Bakudan Campaign.  In February and March 1945, P-40 fighter pilots from 133 Squadron, Royal Canadian Air Force operating out of RCAF Patricia Bay (Victoria, British Columbia), intercepted and destroyed two fire balloons, On 21 February, Pilot Officer E. E. Maxwell While shot down a balloon, which landed on Sumas Mountain, in Washington State.  On 10 March, Pilot Officer J. O. Patten destroyed a balloon near Saltspring Island, British Columbia.  During another interception a Canso forced down a fire balloon which was examined at the army headquarters.  Patrol activity was joined by the Operational Training Schools (OTS) operated by Number 4 Training Command of the BCATP.  They were the No. 3 OTS flying the Canso and Catalina and No. 32 OTS with Ansons, Beauforts and Swordfish at Patricia Bay.  In April, 1944 the No. 5 OTS Heavy Conversion unit stood up at Boundary Bay when 16 B-24 Liberators arrived fresh from American factories.  By the end of September 1944 RCAF 5 O.T.U. had grown to sizeable force of some 87 aircraft including 38 B-24 Liberators, 35 B-25 Mitchells, 5 Bolingbrokes, 8 P-40 Kittyhawks and a single Norseman.  With the end of the war in Europe these aircraft were joined by a number of Victory Aircraft Lancaster X bombers which were to be used to train the British Commonwealth's Very Long Range Bomber Tiger Force that would soon be sent to bomb the Japanese mainland from Okinawa.  With the unconditional surrender of Japan the RCAF's Tiger Force bomber squadrons were disbanded before they flew overseas and the total draw down of the Western Air Command was suddenly undertaken.  Within several months almost all the flying squadrons would be completely stood down.

George G. Finch: Maj. Gen. George G. Finch became the Senior Leader of the US Air National Guard; (Chief of the Air Division National Guard Bureau) (1948-1950) In June 1953 it was reported that Gen. Mark W. Clark would retire and be replaced by Maj. Gen George G. Finch on the UN command delegation to the Korean armistice talks George G. Finch, born April 11, 1902 in Dade City, Florida, is considered one of the pioneers in United States aviation history.  He began his military career during World War 1, enlisting in the Aviation Section of the Army's Signal Corps in 1918.  He remained in the Reserve Corps after the war, and in 1926, became Commander, 27th Pursuit Squadron, 1st Pursuit Group.  In 1940, Georgia Governor Ed Rivers commissioned him to form the first flying unit of the Georgia Air National Guard.  The unit was mobilized into the U.S. Army in September, 1941, with Major Finch as commander.  After World War II, he was a leading critic of efforts to eliminate the air arm of the National Guard during peacetime.  General Finch gained the respect and admiration of Air National Guardsmen throughout the nation with his steadfast support and successful efforts to preserve the Air Guard.  He became the first Chief of the Air Force Division of the National Guard Bureau in 1948.  Under his leadership, the Air National Guard built to combat readiness and was among the first components called into service after the outbreak of the Korean War.  As a result of General Finch's vision and perseverance, 45,000 highly trained officers and airmen of 22 wings and 65 squadrons gave the Air Force the strength it needed in the early, critical phases of the Communist drive down the Korean peninsula.General Finch served as the senior Air Force member of the United Nations negotiating team at the peace talks at Panmunjom, Korea, and received the Legion of Merit for outstanding service in 1955; General Finch assumed command of Fourteenth Air Force, Robins AFB, Georgia, becoming the nation's first Air National Guardsman to head a numbered air force.  General Finch had a career of "firsts" including the US Army's first night landing with a single, five-million-candlepower floodlight in 1927.  He also established and endowed the General John P. McConnell Award at the United States Air Force Academy.  Considered by many as the father of the strong, independent Air National Guard existing today, General Finch retired in 1957.  No man has had greater impact on the Air Force Reserve and National Guard than has General George G. Finch.A graduate of the University of Georgia and a member of the Georgia Bar, General Finch was enshrined in the Georgia Aviation Hall of Fame May 18, 1996.

Chief Master Sergeant of the Air Force: The Chief Master Sergeant of the Air Force (CMSAF) is a unique non-commissioned rank in the United States Air Force.  The holder of this rank and position of office represents the highest enlisted level of leadership in the Air Force, and as such, provides direction for the enlisted corps and represents their interests, as appropriate, to the American public, and to those in all levels of government.  The one exception to the status of the CMSAF as the highest-ranking enlisted member of the Air Force, which has yet to occur, is when an Air Force chief is serving as the Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff.  In this instance, the SEAC would outrank the CMSAF.  The CMSAF is appointed by the Air Force Chief of Staff (AF/CC) and serves as the senior enlisted advisor to the Air Force Chief of Staff and the Secretary of the Air Force on all issues regarding the welfare, readiness, morale, and proper utilization and progress of the enlisted force.  While the CMSAF is a non-commissioned officer, the billet is protocol equivalent to a lieutenant general.

Chief of Staff of the United States Air Force: The Chief of Staff of the Air Force (acronym: CSAF, or AF/CC) is a statutory office ( /8033 § 8033  ) held by a four-star general in the United States Air Force, and is the most senior uniformed officer assigned to serve in the Department of the Air Force, and as such is the principal military advisor and a deputy to the Secretary of the Air Force; and is in a separate capacity a member of the Joint Chiefs of Staff, and thereby a military adviser to the National Security Council, the Secretary of Defense, and the President.  The Chief of Staff is typically the highest-ranking officer on active-duty in the U.S. Air Force unless the Chairman and/or the Vice Chairman of the Joint Chiefs of Staff are Air Force officers.

List of Royal Australian Air Force air marshals: The following is a list of Australians who have attained air marshal rank within the Royal Australian Air Force (RAAF); that is, service personnel who have held the rank of air chief marshal (four-star rank), air marshal (three-star rank) or air vice marshal (two-star rank).  The Royal Australian Air Force was established in 1921 as a separate branch of the Australian military forces.  The service was modelled after the Royal Air Force—formed three years earlier—and adopted the same ranking system.  Richard Williams, regarded as the "father" of the Royal Australian Air Force, was the service's first member to obtain air-officer rank on being promoted to air commodore (one-star rank) in 1927; he went on to become the first air vice marshal (1935) and air marshal (1940).  In 1965, Sir Frederick Scherger became the first officer to be advanced to air chief marshal, one of only four members of the Royal Australian Air Force to obtain this rank as of June 2014.  A further nineteen individuals have reached air marshal in the RAAF and 126 air vice marshal; seven officers have retired with the honorary rank of air vice marshal.
