Question: On what date was the person who sent an emissary rather than attend the 1931 meeting with Luciano and three others in person born? Passage:In April 1931, Salvatore Maranzano, head of the Castellammarese clan in New York City, declared himself capo di tutti capo (boss of all bosses). Lucky Luciano, who opposed Maranzano's claim to control the Luciano crime family, decided to have Maranzano murdered. On April 21, 1931, he met in Cleveland with Frank Milano, Moe Dalitz, Meyer Lansky, Santo Trafficante Sr., and an emissary sent by Al Capone. The five agreed with Luciano's plan to kill Maranzano and establish a new federation of crime families to handle disputes. After the September 10, 1931, assassination of Maranzano, the title of capo di tutti capo was retired and "The Commission" established by the American Mafia. Milano was named a member of The Commission, alongside Joseph Bonanno, Al Capone, Tommy Gagliano, Lucky Luciano, Vincent Mangano, and Joe Profaci.

Question: Who designed Hans Klemm's first light aircraft? Passage:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

Question: How many championships were won by the team Foster signed with in 20001. Passage:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.
