A total of 14 or 15 F-102 fighters were lost in Vietnam. Three were shot down by anti-aircraft or small arms fire, one is believed to have been lost in air-to-air combat with a MiG-21, four were destroyed on the ground during Viet Cong attacks, and the remainder succumbed to training accidents.
Even in peacetime conditions, F-102 pilots risked their lives on every flight. Only highly-qualified pilot candidates were accepted for Delta Dagger training because it was such a challenging aircraft to fly and left little room for mistakes. According to the Air Force Safety Center , the lifetime Class A accident rate for the F-102 was 13.69 mishaps per 100,000 flight hours, much higher than the average for today's combat aircraft. For example, the F-16 has an accident rate of 4.14, the S-3 is at 2.6, the F-15 at 2.47, the F-18 at 4.9, and the F-117 at 4.07. Even the AV-8B, regarded as the most dangerous aircraft in service today, has an accident rate of only 11.05 mishaps per 100,000 flight hours. The F-102 claimed the lives of many pilots, including a number stationed at Ellington during Bush's tenure. Of the 875 F-102A production models that entered service, 259 were lost in accidents that killed 70 Air Force and ANG pilots.
