Question: What kind of aircraft were leased? Passage:In addition to withdrawing from the prestigious long-haul routes to New York and Los Angeles after only 18 months, other specific measures the airline took at the time to ensure its survival included dropping all scheduled flights to Belfast, Copenhagen, Gibraltar, Ibiza, Malaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the GlasgowSouthampton route as well as cutting the number of frequencies on the GatwickGlasgow and GatwickEdinburgh routes from six to four daily round trips. Two surplus aircraft were leased out to Air Malta and Austrian Airlines respectively for the duration of the 1975 summer timetable period. Another aircraft was stationed at West Berlin's Tegel Airport during the month of July of that year to fulfill a short-term charter contract to carry Turkish migrant workers to and from Istanbul on behalf of a local tour operator. BCal also decided to increase its 707 freighter fleet from one to four aircraft and to acquire a five-seater Piper Aztec to serve the rapidly growing executive charter market. These changes left BCal with 25 operational aircraft for the 1975 summer season. To reduce operating costs further, the airline decided to contract out its scheduled operations between Gatwick and Le Touquet to BIA. The reason for replacing BCal's One-Eleven 200 jet aircraft on this route with that airline's Herald turboprops at the beginning of the 1975 summer timetable period was the high price of jet fuel, which had made BCal's own jet aircraft operations uneconomic.

question:
Question: How much profit did AMECON make the year that the Australian government awarded them the Anzac contract? Passage:The Anzac class originated from RAN plans to replace the six River-class destroyer escorts with a mid-capability patrol frigate. The Australian shipbuilding industry was thought to be incapable of warship design, so the RAN decided to take a proven foreign design and modify it. Around the same time, the Royal New Zealand Navy (RNZN) was looking to replace four Leander-class frigates; a deterioration in New Zealand-United States relations, the need to improve alliances with nearby nations, and the commonalities between the RAN and RNZN ships' requirements led the two nations to begin collaborating on the acquisition in 1987. Tenders were requested by the Anzac Ship Project at the end of 1986, with 12 ship designs (including an airship) submitted. By August 1987, the tenders were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later Karel Doorman class) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defense) would build the modified MEKO 200 design. The Australians ordered eight ships, while New Zealand ordered two, with an unexercised option for two more.

Question: What year did Mutual's other popular program, The Lone Ranger, begin airing it's program? Passage:When the Quaker contract expired, Lauck and Goff continued to broadcast on two Texas stations, WBAP (Fort Worth) and WFAA (Dallas). In 1933, The Ford Dealers of America became their sponsor for approximately a year. Horlicks Malted Milk, the 193437 sponsor, offered a number of promotional items, including almanacs and fictional Pine Ridge newspapers. During this period, the show was broadcast on Chicago's WGN (AM), one of the founding members of the Mutual Broadcasting System. Effective July 1, 1935, the program was also carried on WLW (Cincinnati, Ohio), KNX (Los Angeles, California), and KFRC (San Francisco, California). Along with The Lone Ranger, Lum and Abner was one of Mutual's most popular programs. In 1936, Dick Huddleston of Waters petitioned the United States Post Office to change the town's name to Pine Ridge. Postum cereal sponsored Lum and Abner in 193840, before Alka-Seltzer picked up the duo. Miles Laboratories, manufacturers of Alka-Seltzer and One-A-Day Vitamins, became the longest-running sponsor, backing the program from 1941 until 1948. Over the course of its life, Lum and Abner appeared on all four major radio networks: NBC, Mutual, CBS and ABC (formerly NBC Blue).
