bullshit! no they were not! Twin towers 'built to withstand plane crash'

A COMBINATION of catastrophic events caused the downfall of the towering landmark that was built to withstand plane crashes.
The twin towers of the World Trade Centre have gazed out over Manhattan, head and shoulders above most other New York Buildings, for three decades. The revolutionary structures, each 110 storeys high, were built to withstand tremendous pressures and had already survived a 1993 terrorist bombing.
But the immense steel columns in the core - and around the perimeter supporting the enormous buildings - were not enough to prevent them slipping down into a rising fog of dust and debris which engulfed the streets around the city's financial district.
Plans for a world trade facility had been under consideration for many years, but momentum gathered in the late 50s with a site being finally fixed in 1962. The ground-breaking ceremony began four years later and the first tenants moved into one of the towers by the end of 1970, although the building had not been completed. They were declared officially open on April 4 1973.
British consulting engineer Professor Alastair Soane said today: "They were extremely robust buildings and built to withstand a tremendous amount.
"But this was of course a completely abnormal situation and one which would not have been envisaged by the people who built it. The strength of the towers was enormous but they would not have been designed for aircraft strikes.
