What kind of weapon can shoot down a fully loaded passenger jet flying at nearly 33,000 feet? That could be a key question in the Malaysia Airlines Flight 17 crash investigation, as officials try to determine what was responsible for Thursday's plane crash in volatile eastern Ukraine. A radar system saw a surface-to-air missile system turn on and track an aircraft right before the plane went down, a senior U.S. official told CNN's Barbara Starr. And a second system saw a heat signature at the time the airliner was hit. The United States is analyzing the trajectory of the missile to pinpoint where the attack came from, the official said.Senior U.S. official: Radar saw surface-to-air missile system track aircraftA sophisticated surface-to-air missile was more likely used, experts sayOne possibility is the Russian-made Buk missile system, retired Army officer saysThe sophisticated weapon would require professional soldiers, expert says

The first American believed to have been killed while fighting the Islamic State was 'guided to Syria' by God, his father said. Tom Broomfield was speaking out on Wednesday, the day of his son Keith's funeral. The 36-year-old - who died fighting alongside Kurdish forces in Syria - was laid to rest in a private burial, following a service at Grace Baptist Church in Hudson, Massachusetts. Friends described him as a car and motorcycle enthusiast who embraced his passions headlong. They remembered how he drove a DeLorean car in high school and later fixed up a 1970s motorcycle to ride on a cross-country adventure to California.Keith Broomfield, a Massachusetts man who had no military training, was fighting alongside Kurdish forces in SyriaFriends and family gathered Wednesday at Grace Baptist Church in Hudson for his funeral before a private burialHis dad said Keith's path in life had been straightened 'by God'A group of American Kurds also came to show their support.
