I actually asked if they could drop a bunch of bowling balls from planes... like WW2 planes that dropped cannon balls instead of bombs. I was told those types solutions aren’t possible because one explosion could set off several others which then interferes with their carefully plotted (but evidently not particularly useful) map of where the mines are thought to be located. Supposedly the only way to know with 100% certainty that an area is free of land mines is to remove them individually without detonating them. I guess I understand the logic but I also can’t help but think there has to be a better way that’s both cheaper and doesn’t involve humans risking their lives. Perhaps one day.
