How America's new super bomb...

How America's new super bomb works: "For the first time in combat, America has lobbed a still-experimental bomb so fierce it can crush an enemy's internal organs as he hides far beneath the surface of the earth. As heavy as a Volkswagen, these 'thermobaric' bombs are designed to suck the oxygen out of a cave or tunnel, killing even earthworms deep underground. Though the blasts are believed capable as well of wrecking sensitive equipment and destroying chemical weapons beyond the reach of conventional bombs, they are designed to leave the subterranean structure intact so it can later be searched."
