Question: Which of the teams Boswell played for was the oldest? Passage:Born in Chester, Boswell joined local football club Chester F.C. upon leaving school, initially as an amateur. He remained with the club until the outbreak of the Second World War, but never made it to the club's first team.

Upon leaving the army in 1946 he joined Gillingham, who at the time were playing in the Kent League.

Question: Where was the author of the book that Ken Baxter was fascinated with born? Passage:Baxter publicly credits his fascination with the space program to reading From the Earth to the Moon by Jules Verne as a young boy. Baxter holds the distinction of First Founder of Virgin Galactic, a space tourism company announced by Sir Richard Branson on September 25, 2004. Baxter purchased the first commercial space flight ticket at $200,000 USD after viewing a 60 Minutes segment featuring Burt Rutan, winner of the $10,000,000 X Prize for the first non-governmental organization to launch a reusable manned spacecraft into space twice within two weeks, and thereafter, earning him the nickname "Rocket Man". Rutan is also the designer of Sir Richard Branson's SpaceShipTwo, which attached to the mother ship, will be carried to about 16 kilometers or 52,000 feet by a carrier aircraft, White Knight Two. At that point, when the carrier aircraft reaches its maximum height, the SpaceShipTwo vehicle will separate and continue to over 100km (the Karman line, a common definition of where "space" begins). Despite the crash of the first iteration of SpaceShipTwo during a test flight on October 31, 2014, Baxter remains optimistic about his upcoming flight and continues to hold his place at the top of the passenger list to become the world's first commercial space tourist.
