The lost of a Israeli Air Force F-16I from 119 Squadron was probably due to a weight imbalance issue that the pilot was trying to rectify while returning to land at Ramon Air Force Base.

One report said the jet had failed to jettison a live bomb after a strike mission over Gaza and that was the cause of the weight imbalance.
Another report suggest there was an issue with the pilot’s ejection seat which could have failed.
