Question: Who is the mayor of the city that Delta Connection ended service to on May 1, 2008? Passage:In later years, Continental Express continued to serve the airport with nonstop regional jet flights to Cleveland while Continental Connection was operating nonstop turboprop flights to Albany, NY; however, both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur only to drop it soon after. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008 following a mid-April announcement that Delta and Northwest Airlines were planning to merge – a move that led to changes for the merged airline.

Question: When was the library who now own the detailed estates survey drawn by J W Poundley first open? Passage:In the Middle Ages Cilthriew was one of the townships in Kerry. The township is also referred to as Kilroith or Kilroyth. Richard Williams makes the claim that Cilthriew and the neighbouring house of Brynllywarch (which was also a township) were in the ownership of the Pugh (ap Hugh) family from at least 1500. A William Pugh of Kilroith is mentioned in 1632, when he purchased from Ann Foxe, widow of Somerset Foxe lands in Kilroith including Maes y Deynant William Pugh of ‘‘Kilthrew’’ was the Sheriff of Montgomeryshire in 1767 and his son William, who was also Sheriff of Montgomeryshire in 1813, became a very successful attorney and purchased the Caer Howell estate in Montgomery. His son was the notable William Pugh, an entrepreneur, who did much to develop trade and infrastructure in the Montgomeryshire Severn valley. He paid for the final extension of the Montgomery Canal from Berriew to Newtown, and for various road building schemes including a road from Abermule along the Mule valley. In Newtown he encouraged the growth of the textile industry and was responsible for the Flannel exchange, designed by Thomas Penson. In 1828 he sold the Caer Howell estate, using the proceeds to develop Brynllywarch. For this work he may have employed T G Newnham and J W Poundley as his architects and surveyors. His schemes were over ambitious and in June 1835 he fled to Caen in Normandy to escape his creditors. This resulted in the Brynllywarch and Cilthriew estates, which then consisted of 27 farms, being sold in 1839 to Richard Leyland (Bullin), a very wealthy banker from Liverpool. Leyland was to give these estates, together with the Leighton Hall Estates to his nephew John Naylor in 1846. The very detailed survey of the estates purchased by Leyland and later John Naylor, drawn up by J W Poundley, is now in the National Library of Wales. John Naylor died on13th July 1889 and the estates continued in the Naylor family ownership until about 1930, when the various farms including Cilthriew were sold.
