The hijackers attacked at 9:28. While traveling 35,000 feet above eastern Ohio, United 93 suddenly dropped 700 feet. Eleven seconds into the descent, the FAA's air traffic control center in Cleveland received the first of two radio transmissions from the aircraft. During the first broadcast, the captain or first officer could be heard declaring "Mayday" amid the sounds of a physical struggle in the cockpit. The second radio transmission, 35 seconds later, indicated that the fight was continuing. The captain or first officer could be heard shouting:" Hey get out of here-get out of here-get out of here." On the morning of 9/11, there were only 37 passengers on United 93-33 in addition to the 4 hijackers. This was below the norm for Tuesday mornings during the summer of 2001. But there is no evidence that the hijackers manipulated passenger levels or purchased additional seats to facilitate their operation. The terrorists who hijacked three other commercial flights on 9/11 operated in five-man teams. They initiated their cockpit takeover within 30 minutes of takeoff. On Flight 93, however, the takeover took place 46 minutes after takeoff and there were only four hijackers. The operative likely intended to round out the team for this flight, Mohamed al Kahtani, had been refused entry by a suspicious immigration inspector at Florida's Orlando International Airport in August. Because several passengers on United 93 described three hijackers on the plane, not four, some have wondered whether one of the hijackers had been able to use the cockpit jump seat from the outset of the flight. FAA rules allow use of this seat by documented and approved individuals, usually air carrier or FAA personnel. We have found no evidence indicating that one of the hijackers, or anyone else, sat there on this flight. All the hijackers had assigned seats in first class, and they seem to have used them. We believe it is more likely that Jarrah, the crucial pilot-trained member of their team, remained seated and inconspicuous until after the cockpit was seized; and once inside, he would not have been visible to the passengers.

Animated history of the US. Of course the cartoon is highly oversimplified, and most critics consider it one of the weakest parts of the film. But it makes a valid claim which you ignore entirely: That the strategy to promote "gun rights" for white people and to outlaw gun possession by black people was a way to uphold racism without letting an openly terrorist organization like the KKK flourish. Did the 19th century NRA in the southern states promote gun rights for black people? I highly doubt it. But if they didn't, one of their functions was to continue the racism of the KKK. This is the key message of this part of the animation, which is again being ignored by its critics. Buell shooting in Flint. You write: "Fact: The little boy was the class thug, already suspended from school for stabbing another kid with a pencil, and had fought with Kayla the day before". This characterization of a six-year-old as a pencil-stabbing thug is exactly the kind of hysteria that Moore's film warns against. It is the typical right-wing reaction which looks for simple answers that do not contradict the Republican mindset. The kid was a little bastard, and the parents were involved in drugs -- case closed. But why do people deal with drugs? Because it's so much fun to do so? It is by now well documented that the CIA tolerated crack sales in US cities to fund the operation of South American "contras" It is equally well known that the so-called "war on drugs" begun under the Nixon administration is a failure which has cost hundreds of billions and made America the world leader in prison population (both in relative and absolute numbers).

Question: "Which key message(s) do(es) this passage say the critics ignored?"

Problem: You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice.

Question: "How do glaciers form?"

Answer: "By accumulation of snow"

(Financial Times) -- The increasing amount of personal information that can been gleaned by computer programs that track how people use Facebook has been revealed by an extensive academic study. Such programmes can discern undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by Cambridge university academics. In one of the biggest studies of its kind, scientists from the university's psychometrics team and a Microsoft-funded research centre analysed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles. The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion and political leanings. Personality types and emotional stability were also predicted with accuracy ranging from 62-75 per cent. Facebook declined to comment. The study highlights growing concerns about social networks and how data trails can be mined for sensitive information, even when people attempt to keep information about themselves private. Less than 5 per cent of users predicted to be gay, for example, were connected with explicitly gay groups. Michal Kosinksi, one of the report's authors, told the Financial Times that the university's techniques could easily be replicated by companies to infer personal attributes a person did not wish to share, such as sexual orientation or political views: "We used very simple and generic methods. Marketing companies and internet companies could spend much more time and resources, and hence get much higher accuracy than we did." Last week , the EU agreed to water down proposals for a radical overhaul of data privacy regulation. The move reflects governments' reluctance to impede internet businesses that might spur economic growth, and follows fierce lobbying from technology companies including Facebook and Google. Personal data has become big business. Wonga, the UK online lender, makes credit judgments within seconds based on thousands of pieces of information, including an applicant's Facebook profile. Tesco, the supermarket chain, this month started to use its customers' shopping histories to sell targeted online advertising. The report also revealed some unexpected correlations -- such as people who liked 'curly fries' having higher IQs, while those who like Facebook's "Sliding on Floors With Your Socks On" page were unlikely to use drugs.
