Input: Question: How many times did Thomas fumble that season? Passage 1:Surtees was formed by John Surtees after he left BRM to start his own team. He bought a McLaren M7C so that he could use it until the TS7 was ready. The car made its debut at the 1970 British Grand Prix with Surtees driving. He qualified 19th and retired with an oil pressure failure. In Germany, Surtees qualified 15th and was classified in ninth, although his race ended in an engine failure. The Austrian Grand Prix saw Surtees qualify 12th and retire when his engine blew. In Italy, the Englishman qualified 10th and retired when an electrical failure stalled the car at the start. The Canadian Grand Prix saw Surtees qualify and finish fifth. The team owner was joined by Derek Bell as a driver for the United States Grand Prix. Surtees qualified eighth and Bell 13th. The 1964 World Champion retired when his engine blew and Bell finished sixth. In Mexico, the team only entered Surtees. He qualified 15th and finished eighth. 
 Passage 2:After World War II, the Air Force in Hawaii consisted primarily of the Air Transport Command and its successor, the Military Air Transport Service (MATS), until 1 July 1957 when Headquarters Far East Air Forces completed its move from Japan to Hawai‘i and was redesignated the Pacific Air Forces (PACAF). The 15th Air Base Wing, host unit at Hickam AFB, supported the Apollo astronauts in the 1960s and 1970s; Operation Homecoming (return of prisoners of war from Vietnam) in 1973; Operation Babylift / New Life (movement of nearly 94,000 orphans, refugees, and evacuees from Southeast Asia) in 1975; and NASA's space shuttle flights in the 1980s and 1990s. Hickam is home to the 65th Airlift Squadron which transports theater senior military leaders throughout the world in the C-37B and C-40 Clipper aircraft. In mid-2003, the 15th Air Base Wing (15 ABW) was converted to the 15th Airlift Wing (15 AW) as it prepared to beddown and fly the Air Force's newest transport aircraft, the C-17 Globemaster III. The first Hickam-based C-17 arrived in February 2006, with seven more to follow during the year. The C-17s will be flown by the 535th Airlift Squadron.
 Passage 3:Early in the second quarter, Steelers receiver Andre Hastings returned a punt 12 yards to the Bills 43-yard line, setting up Norm Johnson's 45-yard field goal. Now facing a 17-0 deficit, the Bills offense self-destructed on their next drive. Facing 3rd and 8, Jim Kelly was sacked by linebacker Kevin Green and fumbled the ball. Center Kent Hull recovered the fumble for Buffalo, but it didn't help much. On the next play, Lee Flowers stormed into the backfield and tackled punter Chris Mohr on the Bills 12-yard line, leading to another Johnson field goal that gave Pittsburgh a 20-0 lead. Buffalo responded with a drive to the Steelers 30-yard line, only to lose the ball when Lake forced a fumble from Thurman Thomas that was recovered by defensive back Chris Oldham. However, the Bills soon got the ball back with excellent field position after Rohn Stark punted the ball 33 yards to the Steelers 49. Kelly then got the team to the 1-yard line with three completions, hitting Tony Cline for 17 yards, Andre Reed for 5, and Steve Tasker for 26. Thomas then ran the ball into the end zone, cutting the score to 20-7. Only 45 seconds remained in the half, but O'Donnell proved up to the challenge of earning his team some more points, completing 4 consecutive passes for 53 yards to get the team to the Bills 16-yard line. Johnson finished the drive with his third field goal, giving the Steelers a 23-7 halftime lead.
