Radar
On radar:
It seems to me that if a passenger aircraft is flying on established routes and at established flight levels with its transponder deactivated, provided it does not trespass into secure airspace, it will be ignored by military radar and invisible to ATC. This is rather worrying if I am correct.
On flight deck security. Surely it has to be improved now:
1. additional door to prevent anyone following crew through the single door when open i.e. an airlock type system
2. three flight crew, not just two, so that nobody is left alone on the flight deck while someone leaves for a break. The third member could be security instead of pilot.
