[Q]: 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.

[Q]: Question: How many Grammy awards did the singer who re-recorded the song written by Sam Dees win? Passage:In 1983, The Manhattans released the album Forever by Your Side, by Columbia Records, which brought the two singles the group that year. The first was the song "Crazy", the great success of this album, peaked at number 4 on the R&B chart. The second single was the title track "Forever by Your Side", which had moderate success in the United States, peaked at number 30 on the R&B chart, but has become a great success and a romantic classic in Brazil two years later, when it was included as part of the soundtrack of a soap opera in the country in 1985. The success led to a Portuguese version the following year, called "Pra Sempre Vou Te Amar", which also was successful in Brazil, and has been recorded by several Brazilian artists. Another highlight of this album Forever by Your Side was the song "Just The Lonely Talking Again", written by the American singer and songwriter Sam Dees, which was originally recorded by The Manhattans this 1983 album and was later re-recorded by Whitney Houston on her second studio album "Whitney" in 1987.

[Q]: Question: When was the engineer who died in 1904 born? Passage:In addition to the joint railcars of 1903, the London Brighton and South Coast Railway directors asked their Chief Mechanical Engineer, Robert Billinton, to investigate the use of steam or petrol railcars on lightly used services. Billinton died in 1904, before examples could be acquired, but in 1905 his successor Douglas Earle Marsh acquired two steam and two petrol railcars, for comparative purposes with small steam locomotives of the Stroudley A1 and D1 classes fitted for "motor train" or "push-pull" working. The steam railcars were built by Beyer, Peacock and Company and were of a similar design to those supplied by this company to the North Staffordshire Railway. They were stationed at Eastbourne and St Leonards and ran services on the East and West Sussex coast lines. They were both loaned to the War Department in 1918/19 before being sold to the Trinidad and Tobago government.
