[EX Q]: (CNN) A submarine is joining the Mediterranean Sea search for the black boxes that could reveal what caused the crash of EgyptAir Flight 804. The aircraft disappeared from radar last week on a flight from Paris to Cairo. Searchers have recovered parts of the plane wreckage, including passengers' personal belongings, life vests, aircraft chairs and even body parts. But they're still scouring the Mediterranean for the plane's fuselage, and for the flight data recorder and cockpit voice recorder -- key pieces of evidence that would likely reveal what went wrong on the flight. Egyptian President Abdel Fattah el-Sisi announced the deployment of the submarine Sunday. It can reach a depth of 3,000 meters (about 9,800 feet), he said.Mourners at a Cairo mosque gather in memory of the plane's pilotEgypt uses submarine to hunt for flight data and cockpit voice recorders

[EX Q]: (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.

[EX Q]: It's one of the most famous lines in movie history. And now – 40 years after Roy Scheider exclaimed, ‘We’re gonna need a bigger boat’ in Jaws – it seems the film’s director Steven Spielberg has taken the sentiment very firmly to heart. The 68-year-old has announced he is selling his £120 million, 282ft megayacht The Seven Seas... because it is too small. Instead, the Hollywood mogul is having a new boat built, for £160 million. This latest yacht will be just 18ft longer at 300ft, leading some onlookers to question if he needs a new boat at all. The Seven Seas, which was designed by Nuvolari Lenard and crafted by Dutch shipbuilder Oceanco, already boasts an infinity pool with 15ft glass wall doubling as a movie screen, seven suites for up to 12 guests, a helicopter landing pad, gym, spa, and massage room.Hollywood director Steven Spielberg is having a new boat built for £160mMogul claims that his current £120 million, 282ft megayacht is 'too small'Seven Seas boasts infinity pool, movie screen, seven suites and moreBut his new yacht will be just 18ft longer at 300ft for an extra £40million
