<p>This odd looking F-16 was in use as a radar target on a tower, and was raised / lowered when required. It is a composite built from two crashed airframes, and has a huge mounting under the rear fuselage which is where it attached to the tower.
Most of the airframe is from F-16C 84-1228, c/n 5C-65, which was written off on 5th January 1989 after suffering multiple birdstrikes on take-off at Shaw AFB. 
The rear comes from F-16B 78-0105, c/n 62-31, which crashed in the Gulf of Mexico on 27th March 1981 after a fuel pump failure.
Neither of the above accidents were fatal.
The aircraft had recently arrived at the time of our visit.
On display at the Joe Davies Heritage Airpark,
Palmdale, CA, USA.
