Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft. It was an aircraft that in fact had not been hijacked at all. After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked. Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack. NEADS warned the FAA's Cleveland Center to watch Delta 1989. The Command Center and FAA headquarters watched it too. During the course of the morning, there were multiple erroneous reports of hijacked aircraft. The report of American 11 heading south was the first; Delta 1989 was the second. NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it. The flight never turned off its transponder. NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland. But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93. United Airlines Flight 93 FAA Awareness. At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller. This was the last normal contact the FAA had with the flight. Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin." The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming.

Question: "What was the first flight erroneously reported as a hijack?"

Answer: "American Airlines flight 11"

Response: yes

The earliest signs of people on Jamaica are the remains of the Arawak, an AmerIndian society that originated on the north coast of South America. Arawak peoples migrated to various Caribbean islands, arriving in Jamaica by the beginning of the eighth century. They were peaceful and lived by "slash-and-burn" farming. For meat, they bred pigs and ate iguana, both native to the island. They were highly skilled in such manual activities as thatching and weaving. In fact, the hammock was an AmerIndian invention that remains with us today; it is an object which, more than any other, evokes an image of a warm sunny day on a tropical isle. The Arawak left a legacy of paintings in places such as Runaway Caves near Discovery Bay, and shards of pottery found at their settlements near Nueva Sevilla and Spanish Town have added a little to our knowledge about them. Over 200 Arawak sites have been identified, and it is said that when the Spanish arrived in Jamaica there were approximately 100,000 Arawak living on the island. They called Jamaica "Xaymaca" ("land of wood and water"). Columbus and the Arrival of Europeans Columbus first arrived in Jamaica on 5 May 1494 at Discovery Bay, where there is now a small park in his honor. He stayed for only a few days but returned in 1502, landing here when the ships of his fleet became unserviceable; he waited at St. Ann's Bay for help to arrive from Cuba. After the death of Columbus in 1505, Jamaica became the property of his son Diego, who dispatched Don Juan de Esquivel to the island as Governor. Esquivel arrived in 1510 and created a base called Nueva Sevilla near St. Ann's Bay, from which he hoped to colonize the rest of the island. The Spanish immediately began subjugating the Arawak population, many of whom died under the yoke of oppression and of diseases carried by the Europeans. A number of them committed suicide rather than live the life created for them by the Spanish. The site of Nueva Sevilla proved to be unhealthy and mosquito-ridden, and in 1534 the Spanish founded Villa de la Vega, today known as Spanish Town. Pig breeding was the main occupation of these early settlers, but they also planted sugar cane and other crops that required large numbers of laborers. The number of Arawak had already fallen dramatically, so the Spanish began to import slaves from Africa to work the land; the first Africans arrived in 1517.

Question: "Which group of people were highly skilled at weaving and thatching?"

Answer: "AmerIndian"

Response: yes

Early in chapter 5 we introduced, along with Khalid Sheikh Mohammed, two other men who became operational coordinators for al Qaeda: Khallad and Nashiri. As we explained, both were involved during 1998 and 1999 in preparing to attack a ship off the coast of Yemen with a boatload of explosives. They had originally targeted a commercial vessel, specifically an oil tanker, but Bin Laden urged them to look for a U.S.warship instead. In January 2000, their team had attempted to attack a warship in the port of Aden, but the attempt failed when the suicide boat sank. More than nine months later, on October 12,2000, al Qaeda operatives in a small boat laden with explosives attacked a U.S. Navy destroyer, the USS Cole. The blast ripped a hole in the side of the Cole, killing 17 members of the ship's crew and wounding at least 40. The plot, we now know, was a full-fledged al Qaeda operation, supervised directly by Bin Laden. He chose the target and location of the attack, selected the suicide operatives, and provided the money needed to purchase explosives and equipment. Nashiri was the field commander and managed the operation in Yemen. Khallad helped in Yemen until he was arrested in a case of mistaken identity and freed with Bin Laden's help, as we also mentioned earlier. Local al Qaeda coordinators included Jamal al Badawi and Fahd al Quso, who was supposed to film the attack from a nearby apartment. The two suicide operatives chosen were Hassan al Khamri and Ibrahim al Thawar, also known as Nibras. Nibras and Quso delivered money to Khallad in Bangkok during Khallad's January 2000 trip to Kuala Lumpur and Bangkok. In September 2000, Bin Laden reportedly told Nashiri that he wanted to replace Khamri and Nibras. Nashiri was angry and disagreed, telling others he would go to Afghanistan and explain to Bin Laden that the new operatives were already trained and ready to conduct the attack. Prior to departing, Nashiri gave Nibras and Khamri instructions to execute the attack on the next U.S.warship that entered the port of Aden.

Question: "Khallad and Nashri became what position for what group in what years?"

Answer: "Prior to departing, Nashiri gave Nibras and Khamri instructions to execute the attack on the next U.S.warship that entered the port of Aden"

Response: yes

Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water.

Question: "What are the physical properties of matter, and how many primary states are there for matter?"

Answer: "solid and gas"

Response:
no
