That's why they added a specially modified tomahawk control system on board, with special servos to take the cables and simulate the movement of the pilots. Using such system, the plane systems are not modified at all, all systems remain as original, only the automatic servos replace the human pilots for guidance, and their ground interface is standard, identical to tomahawk ground interface.
Such system can remain secret; nobody can notice it. Excellent for that purpose.
Really?
So who installed this super secret system?
At what point in the aircraft's maintenance history did this take place?
How long did it take to perform?
How do you connect this tomahawk flight system to the individual wire looms and actuators, control system and power systems when the two are going to be different specifications?
How big is a tomahawk control system and where in an aircraft could it be fitted? How did "the Jews" get hold of one?
Were the aircraft tested with such systems in place? How and where?
What size of container is needed to hold the required amount of sleeping/nerve/knock out gas you are proposing?
How was this gas delivered and what systems were used? I presume you are saying it was pumped through the air circulation systems. If so how was this gas system installed?
How was the system activated? Was it on a timer? An altitude meter? Remote controlled?
How did maintenance mechanics and engineers for United Airlines or their maintenance subcontractors miss all this extra kit?
You do understand that there are strict protocols for for work carried out at overhaul and that these periods of overhaul/maintenance are carried out by trained personnel to FAA/CAA/UA and Boeing regulations, standards and procedures.
Each inspection/overhaul/change of or to the aircraft would have to be "signed off" not only by the individuals performing the tasks but also inspectors and other engineers.
Are you suggesting an overhaul company or UA overhaul are complicit in this act? If so which one?
I doubt you have answers to these questions. I suggest you do some serious research how aircraft are built and maintained.
