Quick question. Did this lock do exactly what it was meant to do? It appears that despite there being the provision to enter the cockpit from the cabin this provision was in actual fact not available under certain circumstances? How many 320 pilots have passed this potential issue to the next level?
My thought is that post 9/11 the filter for bad should be on the outside of the aircraft and not on the inside. A kneejerk reaction created a double negative.
Surely what has happened in the last 24 hours is further kneejerk reactions that will potentially lead to further (but different) serious issues?
Looking forward to the FDR.
