(CNN)A B-52 crashed Thursday morning at a U.S. Air Force base in Guam during a training mission, with all seven crew members safely leaving the aircraft, the base said.
The huge bomber crashed at Andersen Air Force Base about 8:30 a.m. (6:30 p.m. Wednesday ET); no injuries were reported, the base said.
Details weren't immediately available.
Orange flames and thick smoke rose from a plane's charred remnants at the base, in images distributed by KUAM-TV show.
"The incident is under investigation and measures to mitigate possible environmental impacts are being taken," the base said.
The B-52's home is Minot Air Force Base in North Dakota. The crew members are from the 69th Expeditionary Bomb Squadron.
Military officials have said Guam provides a much different training environment than North America, part of which is the ability to take part in joint exercises.
