The Lao civilian death count was astronomical. US B52 bombers could drop a hundred bombs at a time, and 580,000 bombing missions were conducted. The US dropped a planeload of bombs on Laos every eight minutes, day and night, for nine years from 1964 to 1973. That’s nearly two million tonnes of bombs – over half a tonne of bombs for every man, woman and child living in Laos.
Around a third of the population of Laos was killed, injured or made homeless by the air war – approximately a million people.
This is said to be a bomb crater, NVA or VC were apparently using this area and hence the bombing, the nicest temple was destroyed in one such bombing.
