A knowledgeable source said two small knives were found on a Delta flight that was supposed to depart Boston, and a box cutter was found on an Atlanta-to-Brussels Delta flight. These planes didn\'t take off since all flights were grounded after the hijackings. The tools were found when the planes were searched.
Investigators say they aren\'t sure whether the tools found were intended for some sort of innocent use or whether their owners may have had malicious intent. But they say the two planes\' passenger manifests have been checked. And investigators increasingly believe that the weapons may have been prepositioned by accomplices for use by others. As one U.S. official told Time magazine, "These look like inside jobs."
