Curtiss B-2 Condor

The Curtiss B-2 Condor was a 1920s United States bomber aircraft. It was a descendant of the Martin NBS-1, which was built by the Curtiss Aeroplane and Motor Company for the Glenn L. Martin Company. There were a few differences, such as stronger materials and different engines, but they were relatively minor.

The B-2 was a large fabric-covered biplane aircraft. Its two engines sat in nacelles between the wings, flanking the fuselage. It had a twin set of rudders on a twin tail, a configuration which was becoming obsolete by that time. At the rear of each nacelle was a gunner position. In previous planes, the back-facing gunners had been in the fuselage, but their view there was obstructed. A similar arrangement (using nacelle-mounted gun platforms) was adopted in the competing Keystone XB-1 aircraft.

The XB-2 competed for a United States Army Air Corps production contract with the similar Keystone XB-1, Sikorsky S-37, and Fokker XLB-2. The other three were immediately ruled out, but the Army board appointed to make the contracts was strongly supportive of the smaller Keystone XLB-6, which cost a third as much as the B-2. Furthermore, the B-2 was large for the time and difficult to fit into existing hangars. However, the superior performance of the XB-2 soon wrought a policy change, and in 1928 a production run of 12 was ordered.

One modified B-2, dubbed the B-2A, featured dual controls for both the pilot and the copilot. Previously, the control wheel and the pitch controls could only be handled by one person at a time. This "dual control" setup became standard on all bombers by the 1930s. There was no production line for the B-2A. The B-2 design was also used as a transport.

The B-2 was quickly made obsolete by technological advances of the 1930s, and served only briefly with the Army Air Corps, being removed from service by 1934. Following production of the B-2, Curtiss Aircraft left the bomber business, and concentrated on the Hawk series of pursuit aircraft in the 1930s.

11th Bomb Squadron

The 11th Bomb Squadron is a unit of the United States Air Force, 2d Operations Group, 2d Bomb Wing located at Barksdale Air Force Base, Louisiana. The 11th is equipped with the Boeing B-52H Stratofortress.The 11th is one of the oldest units in the United States Air Force, first being organized as the 11th Aero Squadron on 26 June 1917 at Kelly Field, Texas. The squadron deployed to France and fought on the Western Front during World War I as a Day Bombardment squadron. It took part in the St. Mihiel offensive and the Meuse-Argonne offensive.During World War II the unit served in the Pacific Theater of Operations as a Boeing B-17 Flying Fortress heavy and later North American B-25 Mitchell medium bomber squadron of the Fifth Air Force. During the Cold War it was both a tactical Martin TM-61 Matador and BGM-109G Ground Launched Cruise Missile squadron as part of the United States Air Forces in Europe.

489th Attack Squadron

The 489th Attack Squadron is an active United States Air Force unit, stationed at Creech Air Force Base, Nevada and operating MQ-1 and MQ-9 unmanned aerial vehicles. It was previously active at Beale Air Force Base, California as the 489th Reconnaissance Squadron from 2011 to 2015.

The squadron was first activated as the 77th Aero Squadron in 1917. Redesignated as the 489th Aero Squadron, it served as a support unit in France during World War I before returning to the US and being demobilized in 1919.

Through most of its existence the squadron was named the 489th Bombardment Squadron. It served under this name from 1925 to 1942 in the Organized Reserve. The unit served squadron served in the Mediterranean Theater of Operations during World War II, earning two distinguished Unit Citations for actions in North Africa and Sicily. Inactivated after the war, it served briefly in the reserves a second time between 1947 and 1949. When Strategic Air Command reorganized its Boeing B-47 Stratojet wings as four squadron units the squadron was activated at Whiteman Air Force Base, Missouri, remaining active until 1962.

7th Operations Group

The 7th Operations Group is the operational flying component of the United States Air Force 7th Bomb Wing, stationed at Dyess Air Force Base, Texas. The 7th Operations Group currently flies the B-1 Lancer.

The 7th Operations Group is a direct successor organization of the 7th Bombardment Group, one of the 15 original combat air groups formed by the United States Army before World War II.

Activated in 1921, it inherited the lineage of the 1st Army Observation Group, which was established and organized, on 6 September 1918. The 7th Bombardment Group was deploying to the Philippines when the Imperial Japanese Navy Air Service attacked Pearl Harbor on 7 December 1941. Six of the group's B-17 Flying Fortress aircraft which had left Hamilton Field, California on 6 December 1941 reached Hawaii during the enemy attack, but were able to land safely. The unit later served in India during World War II.

In the postwar era, the 7d Bombardment Group was one of the first USAAF units assigned to the Strategic Air Command on 1 October 1946, prior to the establishment of the United States Air Force. Equipped with low-hour B-29 Superfortress surplus World War II aircraft, the group was inactivated in 1952 when the parent wing adopted the Tri-Deputate organization and assigned all of the group's squadrons directly to the wing.

Reactivated as the 7th Operations Group in 1991 when the 7th Bomb Wing adopted the USAF Objective organization plan.

Air Mail scandal

The Air Mail scandal, also known as the Air Mail fiasco, is the name that the American press gave to the political scandal resulting from a 1934 congressional investigation of the awarding of contracts to certain airlines to carry airmail and to the use of the U.S. Army Air Corps to fly the mail.

In 1930, during the administration of President Herbert Hoover, Congress passed the Air Mail Act of 1930. Using its provisions, Postmaster General Walter Folger Brown held a meeting with the executives of the top airlines, later dubbed the "Spoils Conference", in which the airlines effectively divided among themselves the air mail routes. Acting on those agreements, Brown awarded contracts to the participants through a process that effectively prevented smaller carriers from bidding, resulting in a Senate investigation.

The Senate investigation resulted in a citation of Contempt of Congress against William P. MacCracken, Jr., on February 5, 1934, the only action taken against any former Hoover administration official for the scandal. Two days later Roosevelt cancelled all existing air mail contracts with the airlines and ordered the Air Corps to deliver the mail until new contracts could be let. The Air Corps was ill-prepared to conduct a mail operation, particularly at night, and from its outset on February 19 encountered severe winter weather. The Army Air Corps Mail Operation suffered numerous crashes and the deaths of 13 airmen, causing severe public criticism of the Roosevelt Administration.

Temporary contracts were put into effect on May 8 by the new postmaster general, James A. Farley, in a manner nearly identical to that of the "Spoils Conference" that started the scandal. Service was completely restored to the airlines by June 1, 1934. On June 12 Congress passed a new Air Mail Act cancelling the provisions of the 1930 law and enacting punitive measures against executives who were a part of the Spoils Conferences. Although a public relations nightmare for the administrations of both presidents, the scandal resulted in the restructuring of the airline industry, leading to technological improvements and a new emphasis on passenger operations, and the modernization of the Air Corps.

Curtiss V-1570

The Curtiss V-1570 Conqueror was a 12-cylinder vee liquid-cooled aircraft engine. Representing a more powerful version of the Curtiss D-12, the engine entered production in 1926 and flew in numerous aircraft.

Huff-Daland XB-1

The Huff-Daland XB-1 was a prototype bomber aircraft built for the United States Army Air Corps.

The XB-1 was the first aircraft named using just a B- designation. Prior to 1926, the U.S. Army used LB- and HB- prefixes, signifying 'Light Bomber' and 'Heavy Bomber'. The first XB-1, called the Super-Cyclops by Huff-Daland, was an extension of the earlier Huff-Daland XHB-1 'Cyclops'. It was essentially the same in size, but sported a twin tail and twin engines.

March Air Reserve Base

March Air Reserve Base (IATA: RIV, ICAO: KRIV, FAA LID: RIV) (March ARB), previously known as March Air Force Base (March AFB) is located in Riverside County, California between the cities of Riverside, Moreno Valley, and Perris. It is the home to the Air Force Reserve Command's Fourth Air Force (4 AF) Headquarters and the host 452d Air Mobility Wing (452 AMW), the largest air mobility wing of the Fourth Air Force. In addition to multiple units of the Air Force Reserve Command supporting Air Mobility Command, Air Combat Command and Pacific Air Forces, March ARB is also home to units from the Army Reserve, Navy Reserve, Marine Corps Reserve, California Air National Guard and the California Army National Guard. For almost 50 years, March AFB was a Strategic Air Command base during the Cold War. The facility covers 2,075 acres (840 ha) of land.

Martin NBS-1

The Martin NBS-1 was a military aircraft of the United States Army Air Service and its successor, the Air Corps. An improved version of the Martin MB-1, a scout-bomber built during the final months of World War I, the NBS-1 was ordered under the designation MB-2 and is often referred to as such. The designation NBS-1, standing for "Night Bomber-Short Range", was adopted by the Air Service after the first five of the Martin bombers were delivered.

The NBS-1 became the standard frontline bomber of the Air Service in 1920 and remained so until its replacement in 1928–1929 by the Keystone Aircraft series of bombers. The basic MB-2 design was also the standard against which prospective U.S. Army bombers were judged until the production of the Martin B-10 in 1933.

Martin XLB-4

The Martin XLB-4 was a 1920s proposal for a light bomber by the Glenn L. Martin Company.
