Dear Mike,

Here's one. On September 20, 1965, USAF Captain Philip E. Smith, 436 TFS, 479
TFW (attached to 6252 TFW) Da Nang, flying an F-104C 56-0883, strayed off
course from a combat air patrol over the Gulf of Tonkin following an instrument
failure. He was shot down over China by Chinese MiG-19s and captured.

The incident is told in "Journey Into Darkness" by Col. Philip E. Smith & Peggy
Hertz

Hope this is of some help

Regards
Mike Bennett
