Armed & Fortified Flight Deck
It might be useful to define what is meant by the above.
*Closed circuit video covering the cabin.
*Double door flight deck access - that is, a system which limits access to one person at a time & the second door can't open until the first door is closed.
*Both pilots armed with revolvers firing frangible rounds
Airport Security
