The round that hit Dave Morgan's Tail Fin on 1st May 82 most likely either exploded after it passed though the tail (most impact fused AA warheads are designed to have a short delay so that they explode inside the target if they hit it so that all of the explosive effect does some form of damage) or the deceleration of it going through the skins of the tail was not enough for the fuze to operate.
