I remember that article about the peaceful use of atomic explosions to dig a deep, wide, sea-level canal with no locks. Wasn't it in Life Magazine?
My question then was: what about the fallout and contaminated soil the explosions would throw up? Maybe they could do the explosions underground to just loosen the soil. My question today, looking at the map, is would the canal go through Lake Nicaragua? Is that lake freshwater now? Would connecting it with the sea make it salty?
The article i saw was in either an American Legion or VFW magazine. I'll have to see if I can find it.
