The range for high explosives is generally between 4000 and 10000 metres per second, so a difference of 1600 m/s would presumably affect the results considerably.

The DSTL's forensic explosives lab at Fort Halstead will head the investigation to identify and explain what happened during the explosions.<br /><br />Understandably, the investigators are keeping quiet on the exact details of their work, but explosives experts have suggested that 3D models of the blasts could be used to better understand the dynamics of the explosion.<br /><br />"We could tell them where the device was placed, we'd be able to tell them how much explosive was used," says Neil Fisher, director of security solutions at Qinetiq, the former government defence research lab. "The forensic chemists will be able to tell which type of explosive was used. We understand the science of those explosives, the chemistry, so we can analyse how much explosive was used to cause that much damage."<br /><br />The computer models are created by examining the blast scene and recording the position of every piece of debris. "When you're capturing the real world, you're doing it with a laser and a camera, so the equivalent we use takes 6m data points on each take," says Fisher.<br /><br />"You get a very accurate facsimile of the real world which you can then stitch together to make your simulation."<br /><br />Once the simulation has been created, specific programmes are then run to watch the effects of different types and amounts of explosive.<br /><br />"We would try to match those simulated effects with what's happened in the real world," says Fisher. "Sometimes you'll get blast but not a lot of heat. Others, like Semtex - you can make a lot of heat out of them as well as a blast wave."<br /><br />The modelling is done in two parts. After the simulated blast is compared with the actual event, the information is validated by recreating the explosion for real. "Qinetiq has a large number of ranges and test sites where we are actually licensed to go and do that," says Fisher.<br /><br />Computer models of explosions have a good pedigree in solving terrorist bombing mysteries. The explosion on board Pan Am flight 103, in 1988, was modelled by precursors to the program used by Qinetiq. Investigators showed that it would take only a small amount of plastic explosive - less than half a kilogram in the case of flight 103 - to bring down a Boeing 747.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-350827144131011460.post-8368706600225148042011-02-13T23:03:35.906+00:002011-02-13T23:03:35.906+00:00And, without the virtually valueless apparent afte...<i>And, without the virtually valueless apparent afterthought that was Mahoney's last-minute report on unknown unknowns, and with no autopsy data available, what did the State anticipate presenting to the Inquests?</i><br /><br /><a href="http://www.guardian.co.uk/uk/2005/jul/10/july7.uksecurity10" rel="nofollow">Six key clues to attacks</a><br />The Observer, Sunday <b>10 July 2005</b><br /><br />CCTV<br /><br />London has 6,000 CCTV cameras.
