Input: Consider Input: Question: How many members did No. 11 Group have during the years of the Blitz? Passage: the Second World War, the station was very active during the Battle of Britain and the Blitz in 1940–41 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.

Input: Consider Input: Question: What happens to the length of the leg if there is an abnormal reduction in the angle of the shaft? Passage:The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur is connected to the shaft through the neck or collum. The neck is 4–5 cm. long and the diameter is smallest front to back and compressed at its middle. The collum forms an angle with the shaft in about 130 degrees. This angle is highly variant. In the infant it is about 150 degrees and in old age reduced to 120 degrees on average. An abnormal increase in the angle is known as coxa valga and an abnormal reduction is called coxa vara. Both the head and neck of the femur is vastly embedded in the hip musculature and can not be directly palpated. In skinny people with the thigh laterally rotated, the head of the femur can be felt deep as a resistance profound (deep) for the femoral artery.
