XF-104 "FG-786" 53-7786

XF-104, construction number 083-1001, serial number 53-7786, built by Lockheed

The first XF-104 was accepted by the USAF in November of 1955.
XF-104 number 1 was lost in a crash on July 11, 1957, when it developed an uncontrollable tail flutter while flying chase for F-104A flight tests.
The entire tail group was ripped from the airframe, and Lockheed test pilot Bill Park was forced to eject.
Consequently, no XF-104 prototype survives today.
