We may be safer now from terrorism BUT flying has got much more dangerous due to the locked door policy now in force, apart from the lowering of CRM quality, there is alsothe question of what happens in an emergency if one pilot is incapacitated and the second can't get to the door to unlock it - especially if it was say a pilot collapsing over the controls, second pilot then has to fly the aircraft (AP may get knocked out), get the collapsed pilot off the controls AND try to unlock the door!
