Beirut explosion
ANFO was the preferred explosive in the granite quarry I worked many years ago.
Our powder monkey was very quiet about the technology of his shots.
Drill patterns and charges varied with the amount of destruction they were looking for.
One of my co-workers had a mid 70s D100 with an aftermarket sunroof in it.
The sunroof was the result of a fly rock that a shot launched about 500 yds to the roof of the pickup :lol:.
Lemore NAS was just over a couple ridges from the quarry 100 miles maybe.
The Navy wingnuts used to pass over the quarry at just over tree top level frequently.
One afternoon Alvin has a shot loaded, we closed the yard gathered our personal vehicles and moved to the middle of the yard.
Alvin would take 2 of these
park them side by side with the dump bed towards the shot,
take his detonator and get under the headache rack on top of the engine cover, sound his freon horn and set off the shot 30 seconds later. All present and accounted for Alvin sounds his horn. 15 seconds later I hear the wingnuts before they pass the ridge above the quarry. 15 seconds later Alvin is right on time. The 2 wingnuts were just past the quarry when it detonated. I know they had to feel it. They were so close that the dust from the shot masked our view of them somewhat.
