Its the gunfire and explosives bit that scares me.
Aren't the security measures supposed to stop guns and explosives getting on the aircraft? If the measures fail and guns and explosives DO get aboard, what use is a bomb proof cockpit door going to be? Certainly the aircraft cannot be used as a missile, but we still go back to the old days of airport stand-offs. It all smacks of government washing their hands of proper security and passing the responsibility and cost to the airlines. Apart from the cockpit doors there is the ridiculously expensive video surveillance system to see who or what is outside the door, plus the proposed cockpit pager system for cabin crew (What happens whan they set it off by accident? Automatic diversion? Complete with expensive fighter escort service?) A much cheaper and more effective security method would be to mandate a ban on all carry-on items whatsoever and a proper body search of every passenger at the boarding gate. But such action would be politically dangerous. All those "business-men" with their laptops and lobby power would be really annoyed. Or rather, their bosses would. Not to mention the so-called airport "Duty Free" franchises that actually pay for running the airports.
