Oh boy, what a fruitloop.

So 9/11 was done with remote-controlled aircraft. Care to suggest why the occupants of one of those aircraft rang their families to report terrorists had taken it over? Or are we going on the hypothesis (which we've heard before) that it wasn't them making the calls?

That chip is a gyro, not a control system. It tells you your position. All a "backdoor" into it (assuming one exists) would do is prevent it telling everything else the current position (and hence how to find where it's going). To stop an enemy missile, that's useful. To guide an aircraft somewhere else - well, it just doesn't work like that.

And someone who thinks explosive bolts on doors equals "rigged for remote detonation" - jeez.
