An F-18 fighter jet has fallen off of the carrier USS Harry S. Truman - somewhere in the Red Sea, taking the tractor pulling it along. The pilot and the tractor driver were both rescued, mostly unharmed. It appears the ship may have been taking evasive action under hostile fire when the accident happened.
It is likely a board of inquiry will evaluate this incident to determine if changes in operating policy might be indicated. I don’t know what the tractor cost, the jet had a $56 million price tag.
