Both pilots ejected from the fighter jet before it crashed, but one of them became stuck in the electricity line after his parachute became caught. He was later helped down after power in the area was turned off.
No one on the ground was injured when the jet crashed, which the Belgium Defense Ministry said was due to unspecified engine trouble. The two pilots said there was an "engine technical incident" during flight.
One house was damaged in the incident, according to someone who told The Associated Press their roof was sliced by one of the plane's wings. He said his parents were home at the time, and are OK.
