D-ring:AF type face curtain: navy type

AF F4's had both d-ring and face curtain. But I understand that the d-ring was the AF prefered method.

In late 1967 in was imposible for the A/C if the GIB ejected first----the pilot {A/C} ---- could not eject. The Ventura effect and the 2000#/sq pressure would not eject the canopy.
I can remember debriefing a pilot (Chicago Joe) Had a great line as he tried to punch out in dive with smoke in cockpit 10 times after he order the GIB to eject --- To save my Young ass
i better start flying this aircraft

F4 were mod to add a explosive bolt to remove the canopy
