Input: Question: Who was the older of the two - Joe Airey, or the original member of the radar team that Airey joined? Passage 1:This was the first World Series game ever played in Colorado. At 4 hours 19 minutes, it became the longest nine-inning game in World Series history until game five of 2017. Game 3 was also the 600th World Series game ever played. Starting pitcher Daisuke Matsuzaka pitched five innings of scoreless ball and left in the sixth with no runs allowed. The Red Sox struck first with a six-run third inning. Rookie Jacoby Ellsbury hit a leadoff double, moved to third on Dustin Pedroia's single, and scored on David Ortiz's double. After Manny Ramirez was intentionally walked, Mike Lowell's single scored two more runs. J. D. Drew popped out before Ramirez was thrown out at home on Jason Varitek's single with Lowell advancing to third. After Julio Lugo walked to load the bases, Matsuzaka hit a two-run single for his first base hit and RBI in the Major Leagues. Ellsbury capped the scoring with his second double of the inning to knock Colorado starter Josh Fogg out of the game. The Rockies' bats came to life in the sixth and seventh innings against a normally-solid but now-shaky Boston bullpen. After Matsuzaka walked two straight in the sixth with one out, reliever Javier López allowed back-to-back RBI singles to Brad Hawpe and Yorvit Torrealba. Mike Timlin allowed two straight leadoff singles in the seventh before NLCS MVP Matt Holliday brought the Rockies to within one run with a three-run home run off Hideki Okajima. Brian Fuentes gave back those runs in the eighth by walking Lugo with one out and allowing a subsequent single to Coco Crisp before Ellsbury and Dustin Pedroia, who had four and three hits, respectively, on the night (the first time in World Series history two rookies had at least three hits in a game) hit back-to-back RBI doubles, raising Boston's lead to 9–5. Jonathan Papelbon came on for a four-out save, getting Holliday to fly out on one pitch, leaving runners on first and second. Jason Varitek would tack on Boston's tenth run in the top of the ninth off of LaTroy Hawkins with a sacrifice fly, scoring Mike Lowell who, not generally considered a stolen base threat, had just stolen third base—the first time a Red Sox baserunner stole third base in the World Series since 1975—after hitting a leadoff single and moving to second on a sacrifice bunt. Papelbon came back out in the bottom of the ninth to complete the save, getting the first two outs before surrendering a two-out triple to Brad Hawpe, then finishing the game with a groundout from Yorvit Torrealba. The Red Sox took Game 3 by a final score of 10–5.
 Passage 2:Airey was born in Oldham, Lancashire on 25 August 1894. He joined Robert Watson-Watt in 1924, and was an original member of the radar team, responsible for masts and support equipment. He was Senior Technical Officer at Telecommunications Research Establishment. Alongside Arnold Wilkins, Airey is credited with having discovered Bawdsey Manor, Ordfordnessas a site for the Air Ministry department that was significant in the history of radar. In his book "Three Steps to Victory" Robert Watson-Watt proclaims Joe Airey's greatest constructional achievement as the installation of a mast atop the Great Pyramid at Cheops. During World War I, Airey was a member of the Dunsterforce in the Persia and the Middle East. By the time of his retirement, he was Station Engineer at the Royal Radar Establishment. He was appointed a Member of the Order of the British Empire (MBE) for his services by King George VI in his Birthday Honours on 14 June 1945. Airey died in Poole Dorset on 10 February 1976.
 Passage 3:The Venom entered service with the Royal Air Force (RAF), where it was used as a single-seat fighter-bomber and two-seat night fighter. A dedicated model for aerial reconnaissance was also operated by the Swiss Air Force. The Venom functioned as an interim stage between the first generation of British jet fighters – straight-wing aircraft powered by centrifugal flow engines such as the Gloster Meteor and the Vampire – and later swept wing, axial flow-engined combat aircraft, such as the Hawker Hunter and de Havilland Sea Vixen. Accordingly, the type had a relatively short service life in the RAF, being withdrawn from frontline operations by the service in 1962 as a result of the introduction of more capable designs. However, it was used in combat during the Suez Crisis, the Malayan Emergency, and the Aden Emergency.
