With nowadays modeling and simulation technology it is possible to reproduce the consequence of an IED explosion at 40 kft on a pressurize 747 just by standing in front of a computer. So it is not believable they didn’t evaluate the variables involved in such a scenario.
Or maybe they are just trying to communicate a positive message to everyone who still thinks flying on an airplane is more dangerous then driving a car. Good for the economy and good for airline business!
