Not sure of your question. Particularly the F-4 part.
The F-102 had a major accident rate of almmost 14 per 100,000 hours. It's higher than the AV-8 Harrier rate.
When it was all said and done, 30 percent of the 875(?) F-102s were lost.
That figure of 70 pilots were those lost in F-102s, both US Air Force and Air national Guard.
I'm pretty sure that Bush's unit transitioned to some plane other than the F-4. I want to say Voodoos but I'm not certain.
On 31 January 1972, the 170th Tactical Fighter Squadron/183d Tactical Fighter Group of Illinois Air National Guard became the first Air National Guard unit to transition to Phantoms.
