Ah, thanks for the link WW. The method described by the Banshee pilot is what my dad told me, I got it wrong. They did the loft at near verticle sending the bomb to high altitude and did a Cuban eight, not a split-S to egress.
Dad never did any live ord drops, but his oppinion was the same as the AD pilot. He definately thought if they ever had done a real nuke mission in the A-4 it would have been a one-way trip.
