For the umpteenth time, Crimson faced Bilk has fled to his hangar to cry big red tears on to his plane shaped pillow and hug his little Boeing for consolation. Which gives us a chance to sum up the latest thrashing by looking at videos of what happens when planes hit things. Here's a video of what happens to wings on a C 130 - during a successful landing mind you. So it's traveling quite slowly compared to the mythical WTC plane, and actually lands as planned. The only thing it does wrong is that it tries to pull up too quickly. This causes it to skew to the side a bit, the fuselage lurches, rolls a bit, one of the wing tips touches the ground and snap ! http://www.alexisparkinn.com/aviation_videos.htm#TEST%20FLIGHTS Play the video entitled C-130 SuperSTOL Test Gone Bad -- An example of what not to do when trying to stop short. And as for the tail. You know -the tail which stayed beautifully intact to smash clean through the building - even after the entire fuselage had destroyed itself against the core? We have a fuselage which effectively no longer exists, and hasn't for quite some time, but somehow, the tail is still attached to it and has no trouble bursting through a wall. Normally a tail is attached to a sleekly engineered construction of continuous metal. In the planehuggers imaginary scenario, it is now attached to something which is distorted and crushed into a wildly variable zig zag shape - that's what happens when approximately straight metal things get squashed. >From the link above, here's another video of a hard landing. A successful landing. It's just too hard. The tail breaks off. Play the video called "Hard Landing! -- Ever seen an airliner land so hard that the tail breaks off? You have now! (This was an early DC-9/MD-80 certification test. After this demonstration they beefed up the tail section -- for obvious reasons!)" As you will note, they strengthened the tail section after this test, but considering that they had previously considered it to be close enough that it was worth testing, it doesn't take much to work out that real aircraft tails are not built to stand up to the stress of having the entire fuselage destroyed - with sufficient strength still in reserve to barge their way through a building. How about this 737 accident? http://www.b737.org.uk/accident_reports.htm 25 May 1982; PP-SMY, 737-200 Adv, 20970/376, Del 4/10/74, VASP; Brasilia, Brazil: "The aircraft landed heavily in a rainstorm and broke in two. " Not crashed. "Landed heavily." How about the recent crash of a C130 into a building in Tehran ? You can see one wing of the plane lying at the foot of the building. If the C130 video isn't enough...how strong are plane wings built? The required engineering standard is that "After completing "limit load" tests (ie the maximum loads likely to be experienced by the aircraft during normal service), progressively greater loads have been applied to the specimen towards the required 1.5 times the limit load." http://72.14.207.104/search?q=cache:S_JBoYIAq3IJ:www.freerepublic.com/focus/f-news/1579967/posts+Wing+root+break+breakage Lets review. The fuselage is being squashed, crumpled , like a tin can being trodden on, like an accordion being squeezed. But the wings stay attached. Even though the thing that they are attached to effectively doesn't exist any more in any organized form. Destroying the fuselage that the wings are attached to is apparently within the 1.5 times the load of the wings experience during "normal service". Since wings roots are attached horizontally to the fuselage which is being crushed, then I really like the idea of the wings retaining their structural integrity when the attachment points turn into a zig zag pattern. But it gets better. The stress being experienced must be a *long way* inside the maximum allowable stress limits. It fact this would have to represent almost negligible load, because despite the newly aquired zig zag shape of the wing roots, there's still enough headroom left in the wings capacity for stress that they can now start sawing through steel columns which are used for helping to hold up the world's largest building - and still be within 1.5 times the stress limits experienced by wings during "normal service" - remember that aircraft are built such that it's considered OK for them to break above that level. And considering the dimensions of the core, the plane would start smashing itself against the core, when the wing roots are still at least 15 ft outside the building. The tail is also engineered to withstand 1.5 times normal operating load. So I really like the way that after the fuselage has destroyed itself against the core, it's still firmly enough attached to barge its way through a building. In times to come, assuming the hopeful scenario that the world somehow survives what's going on, and eventually regains some sanity, this will be known as the war of the cartoons, and our generation will be the laughing stock of history.
