The CIA's senior management saw problems with the armed Predator as well, problems that Clarke and even Black and Allen were inclined to minimize. One (which also applied to reconnaissance flights) was money. A Predator cost about $3 million. If the CIA flew Predators for its own reconnaissance or covert action purposes, it might be able to borrow them from the Air Force, but it was not clear that the Air Force would bear the cost if a vehicle went down. Deputy Secretary of Defense Wolfowitz took the position that the CIA should have to pay for it; the CIA disagreed. Second, Tenet in particular questioned whether he, as Director of Central Intelligence, should operate an armed Predator." This was new ground,"he told us. Tenet ticked off key questions: What is the chain of command? Who takes the shot? Are America's leaders comfortable with the CIA doing this, going outside of normal military command and control? Charlie Allen told us that when these questions were discussed at the CIA, he and the Agency's executive director, A. B." Buzzy" Krongard, had said that either one of them would be happy to pull the trigger, but Tenet was appalled, telling them that they had no authority to do it, nor did he. Third, the Hellfire warhead carried by the Predator needed work. It had been built to hit tanks, not people. It needed to be designed to explode in a different way, and even then had to be targeted with extreme precision. In the configuration planned by the Air Force through mid-2001, the Predator's missile would not be able to hit a moving vehicle. White House officials had seen the Predator video of the "man in white." On July 11, Hadley tried to hurry along preparation of the armed system. He directed McLaughlin, Wolfowitz, and Joint Chiefs Vice Chairman Richard Myers to deploy Predators capable of being armed no later than September 1.

You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Question: "What are two examples of static discharge?"

Response: "Lightning, and what happens between you and a door knocker"

Problem: When American 11 struck the World Trade Center at 8:46, no one in the White House or traveling with the President knew that it had been hijacked. While that information circulated within the FAA, we found no evidence that the hijacking was reported to any other agency in Washington before 8:46. Most federal agencies learned about the crash in New York from CNN. Within the FAA, the administrator, Jane Garvey, and her acting deputy, Monte Belger, had not been told of a confirmed hijacking before they learned from television that a plane had crashed. Others in the agency were aware of it, as we explained earlier in this chapter. Inside the National Military Command Center, the deputy director of operations and his assistant began notifying senior Pentagon officials of the incident. At about 9:00, the senior NMCC operations officer reached out to the FAA operations center for information. Although the NMCC was advised of the hijacking of American 11, the scrambling of jets was not discussed. In Sarasota, Florida, the presidential motorcade was arriving at the Emma E. Booker Elementary School, where President Bush was to read to a class and talk about education. White House Chief of Staff Andrew Card told us he was standing with the President outside the classroom when Senior Advisor to the President Karl Rove first informed them that a small, twin-engine plane had crashed into the World Trade Center. The President's reaction was that the incident must have been caused by pilot error. At 8:55, before entering the classroom, the President spoke to National Security Advisor Condoleezza Rice, who was at the White House. She recalled first telling the President it was a twin-engine aircraft-and then a commercial aircraft-that had struck the World Trade Center, adding "that's all we know right now, Mr. President." At the White House, Vice President Dick Cheney had just sat down for a meeting when his assistant told him to turn on his television because a plane had struck the NorthTower of the World Trade Center. The Vice President was wondering "How the hell could a plane hit the World Trade Center" when he saw the second aircraft strike the South Tower. Elsewhere in the White House, a series of 9:00 meetings was about to begin. In the absence of information that the crash was anything other than an accident, the White House staff monitored the news as they went ahead with their regular schedules.

Question: "What was the name of the school where Karl Rove informed President Bush that an aircraft had hit the World Trade Centre?"

Answer: "National Military Command Center knew, but everyone else found out from MSNBC"

Question:
You might want to know how cold it is. You may need to know how fast the wind is blowing. Maybe it rained last night? Do you know how much? Does it feel humid to you? You have heard all these questions before. To answer these questions, we need data. That data comes from special tools. These tools collect data about the weather. You can see some of the common tools listed below: A thermometer measures temperature. An anemometer measures wind speed. A rain gauge measures the amount of rain. A hygrometer measures humidity. A wind vane shows wind direction. A snow gauge measures the amount of snow. After reading the above, is "Hygrometer" the correct answer to the question "What are some common tools?"? OPTIONS:
- no
- yes

Answer:
yes

The dermis is the inner layer of skin. The dermis has blood vessels and nerve endings. The nerve endings explain why your skin is sensitive. You can sense pain, pressure, and temperature. You cut your finger and it starts to bleed. What has happened? If your skin bleeds, it means you have cut the dermis layer and damaged blood vessels. The cut really hurts. It hurts because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. Hair follicles are structures where hairs originate. Each hair grows out of a follicle. Hair passes up through the epidermis. It then extends above the skin surface. Oil glands produce an oily substance. The oil is secreted into hair follicles.

Question: "What extends above the skin surface?"

OPTIONS:
- no
- yes

Answer: "Hair"

Response:
yes
