"Tamper proof." "Fail safe."
This initiative is related to idiot proofing things. The world will always produce a better idiot.
Is there actually a problem? Let us examine, for example, Egypt Air 990.
Some human could get his hands on the power control levers and pull them back when they should have been at altitude happily cruising towards their destination on the eastern side of the Atlantic Ocean. The "Tamper Proof" and "Fail Safe" crowd sugget WHAT solution to that difficulty?
I sincerely hope that they find this hull, and determine whether it was a series of catastrophic systems failures, or something else, that led to its loss. Finding out what did or didn't go wrong might help inform what, if anything, needs remedy.
I am not convinced anything does, other than some of the points raised by those familiar with this model of aircraft concerning the electronics equipment bay perhaps needing more/better fire suppression capability, and perhaps a different access method.
