Question: Which aircraft had a longer operational lifespan in the Royal Canadian Air Force between the McDonnell CF-101 Voodoo and the Avro CF-100 Canuck? Passage 1:The McDonnell CF-101 Voodoo was an all-weather interceptor aircraft operated by the Royal Canadian Air Force and the Canadian Forces between 1961 and 1984. They were manufactured by the McDonnell Aircraft Corporation of St. Louis, Missouri for the United States Air Force (as F-101s), and later sold to Canada. CF-101s replaced the obsolete Avro CF-100 Canuck in the RCAF's all-weather fighter squadrons. The Voodoo's primary armament was nuclear AIR-2A Genie unguided air-to-air rockets, and there was significant political controversy in Canada about their adoption. Although they never fired a weapon in wartime, the CF-101 served as Canada's primary means of air defence from Quick Reaction Alert facilities at Canadian airbases. The CF-101s were retired in the 1980s and replaced with McDonnell Douglas CF-18 Hornet fighters. Many examples are preserved in museums and parks in Canada and the United States.
 Passage 2:In men's singles, on the opening day, play began with the defending champion and world no. 1, Novak Djokovic, dismantling Frenchman Paul-Henri Mathieu. The other top seeds cruised through with 4th-seed David Ferrer winning over Olivier Rochus and 5th-seed Tomáš Berdych over Michael Russell. Last year's quarterfinalist Kei Nishikori also came through over Victor Hănescu. Former finalist Marcos Baghdatis struggled to get past Spaniard Albert Ramos, winning in five sets; another seed in Fernando Verdasco, who was a former semifinalist, was also pushed to his limits, winning in 5 over David Goffin. All other seeds came through with the exception of 11th seed Juan Mónaco who lost to Andrey Kuznetsov after suffering from a back injury. The Australians didn't have a good day with all three that competed in the day losing. The first of which was Matthew Ebden falling to 23rd seed Mikhail Youzhny despite leading 2 sets to 0. His exit was followed by Australian wildcard John Millman who fell also in five to Tatsuma Ito. In the final men's match of the day, 8th seed Janko Tipsarević defeated former world no. 1 Lleyton Hewitt in three tight sets.
 Passage 3:In 1993, Michael Medved wrote in The Sunday Times that "today, comments like Lennon's could never cause controversy; a contemptuous attitude to religion is all but expected from all mainstream pop performers." In 1997, Noel Gallagher claimed that his band Oasis was "bigger than God", but reaction was minimal. Writing for Mojo magazine in 2002, David Fricke credited Cleave's Lennon interview and the "More popular than Jesus" controversy as marking the start of modern music journalism. He said that it was "no coincidence" that Paul Williams, a seventeen-year-old Swarthmore College student, launched America's first serious rock publication, Crawdaddy!, in 1966, given the Beatles' influence and Lennon's "sense of mission" as a spokesman for youth culture. Lennon's comments continued to be the subject of scrutiny in right-wing religious literature, particularly in the writing of David Noebel, a longstanding critic of the Beatles' influence on American youth. According to a 1987 article by Mark Sullivan in the journal Popular Music, a photo from WAYX's Beatles bonfire in Waycross, Georgia, which shows a child presenting the Meet the Beatles LP for burning, became "Probably the most famous photograph of the entire anti-rock movement".
