Let's clear one fact up which is repeated endlessly, and that concerns the fuel element and amounts. You see stated everywhere that because of the fuel, it travelled down the elevator shafts, weakened the steel etc.

Often people state with conviction that the full fuel tanks caused a massive amount of damage. Wrong.

No airline fly's aircraft with more fuel than is needed for, the expected flight plan, the diversion, and a legally required minimum to land with amount.

So far from the aircraft all being laden with full fuel tanks when they hit the towers they did not. The rough figures of the two that hit the towers were about 1/3rd (after the shortened flights) full on impact, maybe slightly over 1/3rd?

And aviation kerosene cannot burn anywhere near enough to melt steel, or even weaken it. It's like saying don't burn wood on your wood burning stove because if you keep it alight for longer than 4hrs the stove will melt, a ridiculous thing to believe. Or limit your gas ring cooker to 2hrs because the grill around it will melt. You get the idea.

Now people talk about the black boxes, but few know about how they work. One ex technician was able to see the data for himself from flight 93's FDR and after years of certifying and examining these recorders he instantly knew that the FDR for flight 93 was a "test bed" box and not fitted to the aircraft?

You see when an FDR (black box) is fitted to an aircraft for the very first time and power through the aircrafts busbar is introduced to it, the very first thing it does (remember this is all back 20+ years ago) is write specific data to its ROM which identifies itself to that specific aircraft. This is important, because you do not want the possibility for FDR's to be mistakenly attributed to any other aircraft other than the one it's fitted too. He could see instantly that the FDR data in the ROM for the aircraft the government told him came from Flight 93 was impossible, because within the ROM the serial number and aircraft ID were all 0's meaning it had never been assigned to an aircraft, during the build, and had never had an aircraft's power running through it from the systems busbar.

Amongst many many other problems, and again what most won't realise is on the FDR's even the cockpit door opening would be recorded, because of the microswitch with the doors mechanism which the aircrafts FDR records.

Flight 93's FDR never showed the cockpit door microswitch being opened at all. Not once in flight. In fact there's so much wrong with just this one FDR that the whole narrative is undone, but you won't hear or read much about these small but crucial facts!
