HE & HEI Rounds that miss, was British cannon ammunition

Greetings All,

After reading Tony Williams' excellent post, and learning that air
craft cannons actually shoot explosive rounds with triggers and fuses,
I have to ask "What happens to the rounds that miss the target?"

Was there a method to insure the round triggered prior to ground
impact? I imagine not...

I only ask as I developed a mental image of a squad of ground troops
diving for cover as rounds from a dog fight miles away finally came to
rest :0


Take Care,
