Question: Hong Kong (CNN) -- Not your average great-great grandfather, Fauja Singh has completed nine 26-mile (42-kilometer) marathons since taking up long-distance running just over a decade ago. On Sunday, the 101-year-old Sikh finished his final competitive race in Hong Kong, putting an end to a sporting career that has raised thousands of dollars for charity and been an inspiration to many around the world. Nicknamed "Turbaned Tornado" by fans for his distinctive traditional headwear, Singh said he began long-distance running in an attempt to lift the depression that engulfed him after he witnessed the death of his son. "I suffered a tragic incident in my life, a traumatic experience; I took up running as a new focus in life. And then marathon running developed from there," he told CNN at a training session before Sunday's race.Fauja Singh, 101, completes final race in Hong KongThe great, great grandfather has run 9 marathonsTook up long-distance running after death of sonAttributes success to love of the sport

Question: (CNN) The unmistakable roar of the A-10's powerful engines echoed throughout Arlington National Cemetery this month as four aircraft saluted retired Col. Avery Kay for the last time with a rare flyover of the historic burial site. Kay, 96, died on October 29 and was buried with full military honors. A highly decorated navigator who led some of the most dangerous bombing raids against Germany during World War II, Kay was also credited with launching the concept of the A-10 Thunderbolt, better known as the Warthog. Despite lacking the air-to-air combat ability of the F-15 Eagle and the high-tech stealth capabilities of the F-22 Raptor, the U.S. Air Force still uses the A-10 to support ground forces in close combat more than 40 years after its first flight in 1975.U.S. Air Force has used A-10 to support ground forces in close combat since 1975Retired Col.

Question: Washington (CNN) Two months ago, the Washington Metropolitan Police Department's new commander, Chanel Dickerson, made a pledge: Let's find our missing girls. Now, as the department posts profiles of missing black and Latina girls in the nation's capital on its Twitter feed almost daily, members of the Congressional Black Caucus are calling for a federal investigation. In a letter Tuesday, the lawmakers asked Attorney General Jeff Sessions and FBI Director James Comey to "devote the resources necessary to determine whether these developments are an anomaly, or whether they are indicative of an underlying trend that must be addressed." "(W)hen children of color go missing, authorities often assume they are runaways rather than victims of abduction," they added.Local police data show 22 missing child cases are open in DC"One missing person is one person too many," DC's police commander said
