As originally envisioned, the 9/11 plot involved even more extensive attacks than those carried out on September 11. KSM maintains that his initial proposal involved hijacking ten planes to attack targets on both the East and West coasts of the United States. He claims that, in addition to the targets actually hit on 9/11, these hijacked planes were to be crashed into CIA and FBI headquarters, unidentified nuclear power plants, and the tallest buildings in California and Washington State. The centerpiece of his original proposal was the tenth plane, which he would have piloted himself. Rather than crashing the plane into a target, he would have killed every adult male passenger, contacted the media from the air, and landed the aircraft at a U.S. airport. He says he then would have made a speech denouncing U.S. policies in the Middle East before releasing all of the women and children passengers.
