Interdisciplinary issues are discussed and human interest programming is broadcast with 'The Forum' and 'Outlook'. Another sports show is 'Stumped', a cricket program about past and current games. Weekends are broken up by sports programming, usually with live commentary on football matches. In addition, there is a selection of science programs, from 'Health Check' to 'Science in Action'. The main part of the schedule is based on 'Newsday', 'Newshour' and 'The Newsroom'. You can listen live or listen again later in the BBC's podcast service. There is also analysis and information from the BBC World Service, which includes a 24-hour worldwide radio network in English and separate services in 27 other languages. Now new photos of the south side of the building, which crucially faced the North Tower, show that whole side damaged and engulfed in smoke.The BBC World Services News Channel has been around since 1932, set up to report from around the world. Until now most of the photographs have been of the three sides of the building that did not show much obvious physical damage. The collapse of the first of the Twin Towers does not seem to have caused any serious damage to Tower Seven, but the second collapse of the 1,368ft (417m) North Tower threw debris at Tower Seven, just 350ft (106m) away. As they heated up the connections failed and the beams sagged and failed, investigators say. Most susceptible were the thinner floor beams which required less fireproofing, and the connections between the beams and the columns. They think fires burnt long enough to weaken and break many of the connections that held the steel structure together. Investigators have focused on the east side where the long floor spans were under most stress. It says Tower Seven had an unusual design, built over an electricity substation and a subway there were many fires that burnt for hours and crucially, fire fighters could not fight the fires in Tower 7, because they didn't have enough water and focused on saving lives. But NIST argues that what happened on 9/11 was unique. Other skyscrapers haven't fully collapsed before because of fire. It requires a level of fidelity in the modelling and rigour in the analysis that has never been done before." Dr Sunder says the investigation is moving as fast as possible. They're confident their approach can now provide the answers. With no steel from Tower 7 to study, investigators have instead made four extremely complex computer models worked out to the finest detail. That's the same kind of time frame that takes place when we do aeroplane crash investigations, it takes a few years." "We've been at this for a little over two years and doing a two or two and a half year investigation is not at all unusual. The National Institute of Standards and Technology has spent more than two years investigating Tower Seven but lead investigator Dr Shyam Sunder rejects criticism that it has been slow. But it said this had "only a low probability of occurrence" and more work was needed.īut now nearly seven years after 9/11 the definitive official explanation of what happened to Tower Seven is finally about to be published in America. In May 2002 FEMA concluded that the building collapsed because intense fires had burned for hours, fed by thousands of gallons of diesel stored in the building.The first official inquiry into Tower Seven by the Federal Emergency Management Agency was unable to be definitive about what caused its collapse. The destruction of the third tower was never mentioned in the 9/11 Commission Report.The third tower was occupied by the Secret Service, the CIA, the Department of Defense and the Office of Emergency Management, which would co-ordinate any response to a disaster or a terrorist attack.Although its collapse potentially made architectural history, all of the thousands of tonnes of steel from the skyscraper were taken away to be melted down.There are a number of facts that have encouraged conspiracy theories about Tower Seven. "Buildings that fall in natural processes fall to the path of least resistance", says Gage, "they don't go straight down through themselves." A sixth grader can look at this building falling at virtually freefall speed, symmetrically and smoothly, and see that it is not a natural process. "Building Seven is the smoking gun of 9/11. The founder of the group, Richard Gage, says the collapse of the third tower is an obvious example of a controlled demolition using explosives.
