OK, let me see if I have this straight. The aircraft manufacturers are supposed to spend millions of dollars designing a transponder that can't be shut off. Then the airlines will spend even more millions retrofitting them to all their planes in service. All because ONE plane lost transponder signal and disappeared??
Will passengers be happy when all that cost gets passed on to them?
And, the planes will have to be rotated out of service to be fitted. When a flight is cancelled because the plane is in the hanger, will the passengers who can't get where they want to be say, "Oh, no problem. At least I won't vanish."
I'd be willing to bet their language will be far more 'colorful'.
