Step five, which happened on July 14. [fact]
Step five, which happened on July 14, 1951, was to fly a B-26 airplane over thirty-one hog pens and drop the experimental bombs, which opened fifteen hundred feet above the ground, releasing a cloud of turkey feathers and blood dust—the release looked like white smoke.
