We don't usually write about what happens in the NPR newsroom. That old line about not wanting to know how the sausage is made certainly applies in most cases.
But if you were tuned in at 11 a.m. ET and the newscast sounded a little different, it's because some technical gremlins got hold of the pre-recorded reports from NPR's correspondents and wouldn't let go. So, it was "live radio" time.
