F/A-18A A21-29 was accepted by the RAAF in April 1988. In May 1990 while deployed to Clarke Air Base in the Philippines a Top Hat and Cane were applied to this aircrafts tail designating it as the C/Os personal aircraft. On August 2, 1990, two F/A-18s (A21-29 and A21-42) departed RAAF Tindal on a practice pairs intercept. Maneuvering during these intercepts can be quite violent when trying to lock onto the target. Unfortunately, A21-42 lost sight of A21-29 and rolled into it killing the A21-42 pilot while A21-29 managed to land safely.
