Question: What years was Billy Hughes the prime minister? Passage 1:Billy Hughes was a former prime minister who had been successively a member of the Labor Party, the National Labor Party, and the Nationalist Party. By 1928, he was the de facto leader of a group of backbenchers hostile to the government of Stanley Bruce (who had replaced him as Nationalist leader in 1923). He and his supporters began to frequently cross the floor and vote against the government, particularly on the controversial subject of industrial relations. On 22 August 1929, Hughes and Edward Mann were expelled from the Nationalist Party for voting in favour of an unsuccessful censure motion against the government. Tensions finally came to a head on 10 September, when Hughes successfully moved an amendment to the government's flagship Maritime Industries Bill. Bruce took this to be a vote of no confidence, and called an election for 12 October. Labor under James Scullin won a landslide victory, while Hughes and two other ex-Nationalists were re-elected as independents.
 Passage 2:In 1993, Vintage Crop made a brief return to hurdling to finish sixth to Granville Again in the Champion Hurdle at Cheltenham Racecourse before being aimed at long distance races on the flat. He won a minor race at Leopardstown Racecourse and the Listed Curragh Cup as well as being placed in the Saval Beg Stakes and the Meld Stakes and finishing sixth in the Ascot Gold Cup. On 18 September, the gelding ran for the second time in the Irish St Leger and started at odds of 9/2 against a field which included Drum Taps and Snurge. Ridden by Mick Kinane, he took the lead approaching the final quarter mile and won by two and a half lengths from Assessor. Vintage Crop was then sent to Australia in an attempt to become the first foreign-trained horse to win the Melbourne Cup. Ridden again by Kinane, the Irish gelding produced a strong run in the straight to overtake Te Akau Nick in the closing stages and win going away by three lengths. The unplaced horses included Subzero, The Phantom and Drum Taps.
 Passage 3:The airline was established in 1993 by Mike Brady of Express Airlines I in Atlanta, Georgia. The airline started operations in August 1993. Its route structure in many ways mimiced an unrelated defunct predecessor named Chicago Air which also operated from Chicago Midway's airport less than a decade before. On June 1, 1999, Chicago Express became a wholly owned subsidiary of Amtran, later known as ATA Holdings and now Global Aero Logistics, and operated as ATA Connection, a regional code sharing affiliate of the now defunct ATA Airlines (formerly known as American Trans Air). Chicago Express' principal base of operations was Chicago Midway International Airport, where the company maintained its headquarters. For several months before its liquidation, the company also operated a hub in Indianapolis, part of ATA's failed plan for intrastate flights throughout Indiana. However, following ATA Holdings' decision to codeshare flights with Southwest Airlines, a decision was made to terminate Chicago Express effective March 28, 2005, in favor of a strictly mainline operation. CSC Investment Group, Inc., headed by CEO Edward S. Halley, purchased the airline in 2005 for $3.2 million.
