What happened to that 'Oxbridge' academic?

[dewstru]

...the one who claimed on a BBC news web page (appx'a year ago?) to have solved the riddle of the twin towers freefall or near freefall collapses largely to dust? (claiming the collapses were unassisted and commensurate with the known laws of physics)Some people here were persuing him quite aggressively . If we could expose just one disinfo shill in the pay of the 'evil-doers' surely the whole rotten edifice would come down...freefall?

Do you mean Dr Keith Seffen?

If so, he seems to have scuttled back into his shell. His mathematical model is different in a number of ways to that which we all saw when the towers collapsed, and I think there is an arithmetical error in his calculations whereby he has omitted the acceleration of gravity, a variable named as 'g', which is 9.81 metres per second per second.

As a result, his equation for 'Resistance', as he reaches his final calculations, appears to have been reduced by a factor of ten. So no wonder he calculates that they collapsed at nearly freefall speeds.

Belated thanks for that, can't we get the beeb to post a PROMINENT retraction of their bogus information from so called Dr Keith Seffen on their website?
