Its actually pretty funny that the author seems to think a "hidden override system" would go unnoticed by technicians.
He, and everyone else promoting the "remote takeover" theory, seem to regard techies as a species of trained monkey, ignorantly perfoming procedures by rote without any understanding of the systems they're working on. I take this, insulting though it is, as an indication of their own utter ignorance.
I'd kinda like for this fellow to pay a visit to my workshop, preferably when I have a piece of tube gear with a nice high voltage plate supply on the bench. I could think of a number of entertaining ways to show him what an ignorant trained monkey I am.
Nice research except for the fact that the ELT is for crashes; its the ATC/TCAS control panel that gets "squawked". I would also like to know how a pilot could set the transponder to 7500 unless the hijackers let him as it takes over 5 seconds(depending on what the code was set at).
Burglar alarms often have a "panic button" function that lets you silently trip the alarm with a single motion and signal the alarm company to send the police. I've turned up a
Notice of Proposed Rulemaking that shows the FAA was considering requiring an analogous arrangement for transmitting the hijack code back in 2003. IMHO, not a bad idea; I don't know if the rule went into effect.
The whole idea of a remote-control capable commercial airliner raises a number of questions in my mind, but there are a couple I'm really curious about.
Let's assume that an aircraft manufacturer does develop a system that would do what folks like Vialls, Valentine and Gaffney fantasize about- take control of the plane away from the normal controls and allow it to be flown to a landing remotely.
A system that's
designed to disable the normal flight controls is, logically, a system whose failure could cause loss of control and a terrible accident. In the regulatory climate airlines operate in, wouldn't such a system be subject to
mandatory scheduled testing and maintenance?
And wouldn't that
require that procedures for that work be written and approved, technicians trained to test, maintain and repair the system, and, possibly, specialized test equipment to be designed, approved, manufactured and distributed?
Wouldn't all of this have to be documented in the technical literature supplied by the aircraft manufacturer to the airlines purchasing their airplanes?
How in the @#$% $^%& (*@# could the existence of this system be kept secret? And
what would be the point of doing so? People who install security systems in their homes and businesses don't generally conceal their existence; it's more common to put up a sign advertising "protected by So-and-So Security" as a deterrent to wannabee burglars.
The knowledge that they absolutely
can't take control of a plane should be a considerable deterrent to would-be hijackers- plus, an airline that could truthfully say "even if the entire flight crew keels over in flight we can get you home safely" probably wouldn't be driving away passengers by doing so.
Or so it seems to me, but I'm just an ignorant trained monkey working in a recording studio.
