The irony is that the pax should get a lot more worried if they are halfway across the pond in a two engined flying machine which suffers an engine failure compared to the same situation on Concorde.
The main problem is that we do not tell the media that flying is potentially risky. If you are going to pack scores of people into narrow tubes and shoot them through the air at 1200 mph supported on wings full of inflammable explosive then nobody should be surprised if very occasionally things go wrong.
There should be a Government Health Warning on all a/c which says something like "Flying is Risky - Possibility of Death of Serious Injury - Only Board if you accept this Risk"!
