Question: How many aircraft did the precursor to Himalaya Airlines have?

 It is the second attempt of Yeti Airlines Group to launch an international airline based in Nepal, following the collapse of Fly Yeti in 2008. Himalaya Airlines (Nepali: हिमालय एअरलाइन्स् , "Himālaya earalāins ") is an airline operating fromTribhuvan International Airport in Kathmandu, Nepal.  Himalaya Airlines was founded in 2014 as a joint venture between Yeti Airlines Group, the Himalaya Infrastructure Fund and Tibet Airlines.  It launched operations in May 2016 with a single Airbus A320.  The airline flies to five destinations as of March 2017. <SEP> The Lindbergh Boom (1927–1929) is a period of rapid interest in aviation following the awarding of the Orteig Prize to Charles Lindbergh for his 1927 non-stop solo transatlantic flight in the Spirit of St. Louis.  The Lindbergh Boom occurred during the interwar period between World War I and World War II, where aviation development was fueled by commercial interests rather than wartime necessity.  During this period, dozens of companies were formed to create airlines, and aircraft for a new age in aviation.  Many of the fledgling companies funded by stock went under as quick as they started as the stock that capitalized them plummeted in value following the Wall Street Crash of 1929.  The Great Depression dried up the market for new aircraft, causing many aircraft companies to go into bankruptcy or get consolidated by larger entities.  Air racing, record attempts, and barnstorming remained popular, as aviators tried to recapture the prizes and publicity of Lindbergh's Transatlantic flight. <SEP> Yeti Airlines Domestic Pvt. Ltd. is an airline based in Kathmandu, Nepal.  The airline was established in May 1998 and received its Air Operators Certificate on 17 August 1998.  Yeti Airlines is the parent company of Tara Air.  Yeti Airlines operates a fleet of seven aircraft and offers domestic flights to ten destinations.  Together, the two airlines form the largest domestic flight operator in Nepal. <SEP> France has used many military aircraft both in its air force, the Armée de l'Air, and other branches of its armed forces.  Numerous aircraft were designed and built in France, but many aircraft from elsewhere, or part of joint ventures have been used as well.  Lighter-than-air aircraft such as dirigibles and balloons found use starting in the 19th century used mainly for observation.  The advent of World War I saw an explosion in the number France's aircraft, though development slowed after.  While having many promising designs in development in the 1930s, government wrangling delayed development enough there was little available at the out break of World War II.  The armistice in 1940 marked a low point, with Vichy France being allowed only reduced numbers and development halting.  Many French aircraft were captured and used by the Third Reich and its allies.  Some aircraft that did escape served with the Allies or Free French forces, who also used many other types of allied aircraft.  The cold-war saw the continued use of many other Western aircraft, mainly from the U.S., during a period of rebuilding of the aviation industry and under threat of war with the Soviet Union.  Many new types would come into service including the very successful Mirage series or the latest design, the Rafale.
