I'm afraid that in all of this I have to go with Guppy.
Just this weekend a 744 departed LHR with a door warning light on. He came around for an expeditious return. End of story, except it made the front page of the Sunday tabloids.
The two poor guys who lost their lives in DXB were dwarfed in the news by the parachute aircraft that crashed the following day in NZ. Not only in the news but also in the industry. The bean counters saw two deaths in a cargo a/c and nothing more. Their thoughts were pay up if necessary and move on.
There's enough difficulty in X-raying pax bags on selected flights before there will be money spent on X-raying any cargo a/c loads. This is now an instant world and folks aren't going to wait for (literally) shipping when they've been used to flying freight delivery times.
More vigilance from the crews will alleiviate some of the problem. Just as we check loadsheets carefully so should we check the load itself and know what we're carrying. Cos nobody else will give a care. And that's whether it's been loaded correctly or not or whether we reach destination or not.
