Should the arline industry accept any blame for the success of the 9/11 attacks?

I think the ext to which airlines industry  can be blamed
for the 9/11 attack, is no more than the extent to which a brick, which has been used to
hit a person, can be blamed for hurting the person. But the the brick is an inanimate
object, while airlines industry is an organization of people, and it would be great
folly for those men from airlines industry to not to accept the responsibility for
preventing such possibilities in future.

I cannot say that
airlines industry has now made it absolutely impossible for terrorist to use air travel
to perpetuate terrorism in any way, but they appear to have accepted their
responsibility to prevent terrorism and are taking many positive actions to curb use of
airlines for terrorism.
