Investigators say the crash of a military jet in Spain that killed 11 people was due to a technical problem during takeoff.
They say the crew of the Greek F-16 fighter jet had attempted to eject.
Among the dead were nine French personnel on the ground and the two Greek pilots.
More than 20 other French and Italian air force officers were injured and several remain in a critical condition.
The exact nature of the technical problem has not been disclosed and officials say a full inquiry is continuing.
The accident happened during a NATO exercise at the Los Llanos military base in Albacete.
The crash on Monday was described as the worst loss of life during a NATO exercise in living memory.
Witnesses say the jet lost power and then crashed into half a dozen other jets on the ground, resulting in raging fires.
