Ok, good everyone knows it WASN't a 767-400 that hit it
Now only the -300 vs -400. The plane that hit one of the WTC was N334AA, if you beleive it was a missle; I think you should figure out what really happened to N334AA.

Is there any photo with "trade marks", airline name or something like that of this plane ?

The whole problem though is that at least one of the two flights was tracked all the way on radar, and no radar returns were anywhere near it. So when and how did they replace it?

Thx. Do you have some photos of "normal" plane from this airlines not from 911 ?
Who overrode Flight 175's onboard computers?
Modern planes are complicated creatures that incorporate a whole slew of sophisticated technology. First among them, flight computers that instantly override any accidental brusque manoeuvres; you don't want your business-class customers slopping their Dom Perignon over their immaculate suits, just because the pilot sneezes at the wrong moment.
The banking manoeuvre we see here, just as flight 175 is about to slam into the South Tower, would have been overridden by the onboard flight computer. So somebody must have previously overridden the flight computers themselves.

Uhm, no they don't. They mght on a Fly By Wire system, but the 757 and 767 are a link and pulley system. The only thing limiting the manuvers in them is the pilots strength.
The complexity and weight of a mechanical flight control systems increases considerably with size and performance of the airplane. Hydraulic power overcomes these limitations. With hydraulic flight control systems aircraft size and performance are limited by economics rather than a pilot's strength.
A hydraulic flight control systems has 2 parts:
The mechanical circuit
The hydraulic circuit
The mechanical circuit links the cockpit controls with the hydraulic circuits. Like the mechanical flight control systems, it is made of rods, cables, pulleys, and sometimes chains.
The hydraulic circuit has hydraulic pumps, pipes, valves and actuators. The actuators are powered by the hydraulic pressure generated by the pumps in the hydraulic circuit. The actuators convert hydraulic pressure into control surface movements. The servo valves control the movement of the actuators.
The pilot's movement of a control causes the mechanical circuit to open the matching servo valves in the hydraulic circuit. The hydraulic circuit powers the actuators which then move the control surfaces.
This arrangement is found in most jet transports and high performance aircraft. These include the Antonov An-225, the Lockheed SR-71 and most aircraft in-between.
