Yes, yes, yes, firm adherence to SOPs and checklists, killer items especially, should preclude any such accident, but the fact remains that people screw up from time to time, even the highly trained and experienced.
The TOWS is a backstop to the crew. But what I see here is a vital backstop that can very easily be bypassed without knowing that that has happened.
Put me in the camp of those who agree that it should be checked on every flight, especially as we have seen how easy it is to inadvertently disable it.
But I still want to see it harder to disable this system -- or some obvious indication on the breaker that it supplies a flight critical system.
