Would like to put my two bob’s worth in if I may.
It has always intrigued me how an aircraft could just ‘bury’ itself into a building. Maybe there is someone out there who could explain this to me.
I have a long history working with heavy earthmoving machinery, including manufacture of ground engaging components, steel rakes and timber handling equipment for bulldozers etc. So I do have a little bit of an idea of metal construction though do not have any engineering qualifications.
I have absolutely no knowledge of aircraft construction / manufacture, maybe there is someone out there who could enlighten me in this matter. I assume, aircraft wings, and tail for that matter, are manufactured of a lightweight material, maybe aluminium.
The documentary’s I’ve seen on telly, re the construction of the towers, have shown how the steel beams ‘failed’ due to the impact of the aircraft and subsequent explosion. My main interest here is: the buildings were constructed with steel beams in a recognised / accepted / proven engineering manner, which had never failed prior to 9 /11, so they say, a very strong and stable construction.
I understand how the villosity of impact could amount to an aircraft being able to penetrate the buildings to a certain degree, but I don’t understand how it could be completely ‘buried’ into the building. I can’t see how the wing tips would penetrate a steel construction let alone the tail section doing the same thing, disappearing into the building that is.
I think, someone help me out here, the tail of these aircraft, that reportedly hit the towers, stands quite a bit higher than the fuselage of the craft, would not the tail section of the aircraft be travelling at quite a reduced speed than the nose of the craft on impact, making it just about impossible to have enough villosity to enter the building, acknowledging the impact area of the tail is quite higher than the hole in the building where the fuselage entered. Would not the tail be left on the outside of the building?
I realise the explosion prevents us seeing much of what happens when the aircraft impacts the tower, maybe there is someone out there who is skilled enough to be able to ‘slow’ the film down so as to be able to see the wings and tail section enter the building. My thoughts are, these lightweight sections of the aircraft would have to break away from the fuselage on impact, not disappear into the building.
Maybe I have all this wrong, just a thought.
(no thoughts on hologram’s, that stuff is way beyond me)
