C-17 Globemaster Elmendorf AFB Alaska crash update

The C-17 that crashed at Elmendorf Air Force Base in Anchorage, Alaska, is now the focus of a U.S. Air Force investigation.

The Boeing military cargo plane, one of 199 in operation around the World, according to FlightGlobal.com, crashed yesterday at 6:14 PM local time.

The C-17 was making a rehearsing flight plan as part of an air show called The Arctic Thunder Air Show, but what went wrong to cause the giant plane to crash, causing a plume of smoke seen for two miles and as high as 750 feet in the air, is not known. Hence the investigation.
