It has been pointed out . . .

. . . that even though the Yanks are claiming their MOAB was the biggest bomb dropped since Hiroshima, in typical bloody Yank fashion, it’s not as heavy as the 22,000 lb Grand Slam developed by Sir Barnes Wallis of dam-busting, bouncing bomb fame. The RAF was unloading these earthquake bombs against difficult targets at the end of WW 2. Which means that if the Guinness Book of Records changed its policy on excluding weapons, the US MOAB wouldn’t get a look-in, seeing it’s 70 years late and not heavy enough.
