Are we ruining years of CRM training with the advent of a cockpit door built like a fortress? I see the reason why they were installed on our airplanes but is it actually increasing or decreasing overall safety? Sure it would be harder for a hijacker to gain access to the flightdeck but I believe it is reducing the communication lines between us and the cabin crew, thereby reducing CRM.
Now, the question is what is more benificial for safety? Reducing the chance of stopping a very rare hijack attempt or keeping the lines of communication flowing thereby increasing Total CRM effectiveness.
I believe the CRM aspect of it is more important and if kept up will help overall safety.
