The indignations Steve is that Germanwings is the tip of the unspoken Elephant in the room...i.e. All the security checks in the world dont prevent deaths by a pilot who already has control of a deadly weapon. Its been an insulting joke for years....that coffee cant take that....even if you get coffee on board...cant take that golf club....but for the fire axe in the cockpit is still sitting there.
To calm the public, we are seen to be doing something but it actually doesnt do much. And thus the indignation in the majority of the posts.
