The Stars and Stripes reports the F-15E Strike Eagle that crashed in March in Libya was brought down due to a weight imbalance.

An Air Force investigation into what caused the crash of an F-15E Strike Eagle during a night combat operation over Libya last March has concluded that a weight imbalance was a major factor…

The situation deteriorated rapidly after the pilot dropped his bomb.

“He dropped it and was getting out of there,” Shapiro said. “Halfway into the maneuver is when he went into the spin.”

The aircraft never recovered, and the crew ejected.  The pilot was recovered by Marines while the WSO was sheltered by rebels.
