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, Málaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the Glasgow—Southampton route as well as cutting the number of frequencies on the Gatwick—Glasgow and Gatwick—Edinburgh 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: Is the fort built to protect Philadelphia on the Pennsylvania side still standing? Passage:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Question: What regiment was the commander of the Tiger tank that cut off the Rifle Brigade from? Passage:The regiment landed in Normandy on 7 June 1944, the day after D-Day. During the Battle of Normandy, 4th CLY served as part of the 7th Armoured Division. On 13 June, they led the advance of 22nd Armoured Brigade with A Company of 1st Battalion, Rifle Brigade (Prince Consort's Own) by road from Villers-Bocage and were ambushed by a detachment comprising five Tiger tanks. One of the Tigers, commanded by SS-Obersturmführer Michael Wittmann, cut in behind the lead squadron, cutting them off and destroying the soft-skinned vehicles of the Rifle Brigade before running into the Sharpshooters Headquarters Troop and accompanying artillery observation tanks. Wittmann is credited with up to ten of the kills before his tank was immobilised and he escaped on foot. The cut-off squadron was later forced to surrender after the arrival of a further ten Tiger tanks. These Tigers, with elements of Panzer-Lehr-Division and 2nd Panzer Division, then counter-attacked the British in the town, but lost up to eight Tigers and two Panzer IVs before the British withdrew. 4th CLY lost its commander, Lieutenant Colonel The Viscount Cranley, and second-in-command; "A" Squadron was destroyed. 4 CLY's losses for the day amounted to 20 Cromwells, four Fireflys, three Humber Scout Cars, three Stuarts and a half track.
