This article in Slate by Fred Kaplan is really impressive. Most of the time news people don't seem to want to make a big deal of each others mistakes. It's almost like they're hoping for the same treatment in turn. Fred Kaplan must plan to try and avoid making any.

First, it's big, but not that big. On the night of the test, ABC News reported that the bomb was "similar to a small nuclear weapon." Time magazine, in strikingly similar language, reported that it "packs the punch of a small nuclear weapon." Let's do the math. The MOAB weighs 21,000 pounds, including 18,000 pounds' worth of high explosives. That's 9 tons. The teeniest nuclear weapon in the U.S. stockpile has the blast-power of 1,000 tons (one kiloton, in the parlance). In other words, had Time's reporter been a bit less giddy, he would have written that MOAB (which, by the way, the Air Force pronounces "mo-ab") "packs one one-hundredth the punch of a small nuclear weapon."
