So when you pulled the trigger or pressed the button or whatever it was. How did you know at that moment where the shell would land and who was under it?
Actually, the only time I got to push the button was during target practice in Hawaiian waters, where the target was an uninhabited island. Normally, I had nothing to do with that as my job had to do with a missile system. Still, I did get to fire what might be considered a huge machine gun (a 5"/54 naval rifle) as I got to fire "five rounds, rapid continuous."
You are old. It does not appear you have learned to love life. I hope you find some peace in this world before you leave it.
Yes, I'd call myself old at 76, and do, but I have many wonderful memories to cherish, such as watching both an annular and a total eclipse of the sun, seeing a lava fountain on the Big Island during an eruption from Honolulu, and seeing the Grand Canyon, Half Dome and Fishers Peak. What memories are you storing up for your Golden Years?
