Input: Question: Which country manufactured the damaged aircraft that the searchlight crew saw crash into the sea? Passage 1:As Chancellor Kohl was strongly committed to European integration and FrenchGerman cooperation in particular; he was also a steadfast ally of the United States and supported Reagan's more aggressive policies in order to weaken the Soviet Union. Kohl's 16-year tenure was the longest of any German Chancellor since Otto von Bismarck. He oversaw the end of the Cold War and the German reunification, for which he is generally known as Chancellor of Unity. Together with French President Francois Mitterrand, Kohl was the architect of the Maastricht Treaty, which established the European Union (EU) and the euro currency. Kohl was also a central figure in the eastern enlargement of the European Union, and his government led the effort to push for international recognition of Croatia, Slovenia, and Bosnia and Herzegovina when the states declared independence. He played an instrumental role in solving the Bosnian War. Domestically, Kohl's policies focused on economic reforms and later also on the process of integrating the former East Germany into the reunited Germany, and he moved the federal capital from the "provisional capital" Bonn back to Berlin, although he himself never resided there because the government offices were only relocated in 1999. Kohl also greatly increased federal spending on arts and culture. After his chancellorship, Kohl's reputation suffered domestically because of his role in the CDU donations scandal and he had to resign from his honorary chairmanship of the CDU after little more than a year in January 2000, but he was partly rehabilitated in later years. The later Chancellor Angela Merkel started her political career as Kohl's protegee.
Passage 2:By August 1940 the Battle of Britain was intensifying. Most of the battles thus far were in daylight, leaving night-fighter crews frustrated. Now based at RAF Digby in Lincolnshire and operating from the satellite airfield at Wellingore the unit formed part of No. 12 Group RAF defending British air space north of London. On the night of 24 August 1940 Braham took off and patrolled the Humberside area. The Blenheim was piloted by Braham, and contained air gunner Sergeant Wilsdon and aircraftman and trained radar operator N. Jacobson. Braham was directed to an aircraft held in searchlights but he closed too fast and overshot. His gunner succeeded in damaging the aircraft sufficiently and a searchlight crew saw it crash into the sea. It was identified as a Heinkel He 111. Braham's only other interaction with the enemy occurred at Ternhill, when a Junkers Ju 88 dropped bombs on the airfield destroying 13 Avro Ansons and damaged 20 more. Braham survived the attack uninjured.
Passage 3:In 1971, Bob Shad, who had worked with her as producer at Mercury, asked her to record for his label, Mainstream, which he had founded after leaving Mercury. Breaking a four-year hiatus, Vaughan signed a contract with Mainstream and returned to the studio for A Time in My Life, a step away from jazz into pop music with songs by Bob Dylan, John Lennon, and Marvin Gaye arranged by Ernie Wilkins. She didn't complain about this eclectic change in direction, but she chose the material for her next album after admiring the work of Michel Legrand. He conducted an orchestra of over one hundred musicians for Sarah Vaughan with Michel Legrand, an album of compositions by Legrand with lyrics by Alan and Marilyn Bergman. The songs brought some of the musicians to tears during the sessions. But Shad wanted a hit, and the album yielded none. She sang a version of the pop hit "Rainy Days and Mondays" by the Carpenters for Feelin' Good. This was followed by Live in Japan, her first live album since 1963. Sarah Vaughan and the Jimmy Rowles Quintet (1974) was more experimental, containing free improvisation and some unconventional scatting.
