Question: What country is the Bristol Channel located in? Passage:Because of the natural layout of the harbour, Ilfracombe became a significant safe port (registered port of refuge) on the Bristol Channel. It also had trade routes between Kinsale and Tenby, which made the port stronger. In 1208 it was listed as having provided King John with ships and men to invade Ireland; in 1247 it supplied a ship to the fleet that was sent to conquer the Western Isles of Scotland; 6 ships, with 79 men were sent to support the siege of Calais. Ilfracombe was the last disembarkation point for two large forces sent to subdue the Irish. The building which sits on Lantern Hill by the harbour, known as St Nicholas's Chapel (built 1361) is reputed to be the oldest working lighthouse in the UK; a light/beacon has been there for over 650 years. The town was also home to the Bowen family. James Bowen was master of HMS Queen Charlotte, the flagship of Richard, Earl Howe at the 1794 "Glorious First of June" battle. James Bowen was commissioned by Howe for his leadership in the battle, he rose through the levels - commander of the Argot, the Dreadnought, and in Georgian England titled "defender of Madeira", led the fleet which rescued the British army at Corunna in the Peninsula war, and retired as a Rear Admiral, Commissioner of the Royal Navy. Captain Richard Bowen (17611797) James Bowen's younger brother, a British naval commander on the ship HMS Terpsichore, served under Lord Nelson, and was killed at the battle of Santa Cruz de Tenerife. John Bowen (17801827), son of James Bowen, a naval officer and colonial administrator founded the first settlement of Tasmania at Risdon Cove in 1803 - the settlement which later became known as Hobart. Lieutenant A E Down, was initially posted to Ilfracombe to lead a protection ship for the customs and excise, he married a local girl, rose through the levels to retire as vice Admiral, his son joined the navy aged 14 (his first navy kit is on display at National Maritime Museum Greenwich). In 1802 James Meek married Down's daughter and settled in the town, James Meek was appointed the Comptroller of Victuals to the Royal Navy in 1832, he was knighted, and died in Ilfracombe 1852.

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 $100million 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.
