Narrative:
Written off 17 November 1999 when collided with F-16 86-0263 1.2 miles west-north-west of Vermont, illinois. F-16C 86-0263 returned to Springfield ANGB undamaged.

According to the following extract from the summary of the official USAF report into the incident:

"Collided with F-16C (86-0263), near the town of Vermont, Illinois. One pilot landed the aircraft while the other was forced to eject. Cause is believed to have been from one of the pilots losing situational awareness.

The mishap occurred as the upgrading pilot performed an air-to-air intercept on the instructor who was acting as a target and flying slow speed with lights out. A high to low intercept was flown by the upgrading pilot and he did not achieve sufficient lateral displacement for his Vc (overtaking velocity). He rolled out behind the target at 500 feet and 180 knots of overtake.

An evasive manoeuvre was initiated at 200 feet and less than 1 second prior to impact. The right wing impacted and severed the target aircraft's left horizontal tail and severely damaged the corresponding hydraulic integrated servo actuator. The aircraft then experienced total hydraulic failure and went out of control.

The instructor pilot ejected safely and the upgrading pilot flew his damaged aircraft to base."
