As a ground handler I agree with much said here. However, it does rely on good and efficient handling and I can assure you that in many airports that is not the case.
Those servicing the a/c at ground level also need to be committed to the safety factors at all times and often it does not happen as it should.
This is reflected in the numerous incidents of loading 'dangerous' cargo incorrectly, damage, chute deployment.
There is still a culture of 'wing and a prayer' I fear.
