Q: Question: When did the war begin that prompted the Navy to build the airport? Passage:In 1950, Admiral Arthur W. Radford, Commander-in-Chief of the United States Pacific Fleet, envisioned an naval base in the Western Pacific to enhance Seventh Fleet capabilities. The Korean War began and the Navy realized it had a need for an air station in the region. Cubi Point in the Philippines was selected, and civilian contractors were initially approached for the project. After seeing the Zambales Mountains and the surrounding jungle, they claimed it could not be done. The U.S. Navy then turned to the Seabees and was told no problem, Can do. The first Seabees to arrive were surveyors of Construction Battalion Detachment 1802. Moblie Comstruction Battalion 3 arrived on 2 October 1951 to get the project going and was joined by MCB 5 in November. Over the next five years, MCBs 2, 7, 9, 11 and CBD 1803 also contributed to the effort. They leveled a mountain to make way for a nearly runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal. Seabees there moved of dry fill plus another 15 million that was hydraulic fill. The $100 million facility was commissioned on 25 July 1956, and comprised an air station with an adjacent pier capable of docking the Navy's largest carriers. Adjusted-for-inflation, today's price-tag for what the Seabees built at Cubi Point would be $906,871,323.53. After decades of use by American forces, Mount Pinatubo erupted in 1991, burying Cubi Point in 18-36 inches of ash. Despite this, the American government wished to keep the Subic Naval Base and signed a treaty with the Philippine government. The treaty was not ratified, however, failing by a slim margin in the Philippine Senate. Attempts to negotiate a new treaty were soon abandoned and the United States was informed that it was to withdraw within one year. U.S. forces withdrew in November 1992, turning over the facility with its airport to the Philippine government.


A: The Korean War began and the Navy realized it had a need for an air station in the region

Q: Question: In what year was the house the Vogtei went to after the Lenzburg family established? Passage:The first mention of modern Hägglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromünster. In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned. Frederick I Barbarossa acknowledged the grants to the village in 1173. The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl. The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415. It was not until 1425 that Hägglingen, which was claimed by Lucerne, came under the authority of the entire Confederacy. It was first assigned to the district court of Wohlenschwil before it became an independent municipality from 1435-1712.


A: The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl
