Well I hope you are right but I dont necessarily agree with your assessment of the danger of pocket knives on planes now just because they have locks on doors and attitudes of people now being such that current flyers would not tolerate what happened on 9/11. If a group of attackers like on 9/11 had pocket knives to the throats of all of the flight attendants I would think that would be a serious threat, yes if there were enough able bodied people to form an attack on the terrorists than Im sure they could overcome them but at the expense of what the slit throats of all of the flight attendants. There are many people that wouldnt be able to overcome the mental hurdle of knowing that any attack would likely result in the death of the flight attendants.don't see a relationship between the two circumstances.
Hurting or even killing someone with a pocket knife will not get you into the cockpit these days, and injuring or killing one or two people on a plane won't be perceived by anyone as justifying drone strikes in the U.S.
A pocketknife with a non-locking 2.36 inch blade also won't get you very far with flight crew or passengers. A determined attacker could slash a few people, but the post 9/11 response of the rest of the passengers would be overwhelming and decisive.
The TSA decision looks like just a rare moment of lucidity in line with the removal of the bans on things like eyebrow tweezers and hairpins. The motivation is being sold as risk based, but it appears more likely to be motivated by a desire to reduce workload and increase throughput at checkpoints by eliminating the need to open bags and confiscate things that have little potential weapon value.
Clearly the flight attendants union thinks that this is a serious issue this is a quote from them:
“Today’s announcement to permit knives back into the aircraft cabin is a poor and shortsighted decision by the TSA,” the group said in a statement. “As the last line of defense in the cabin and key aviation partners, we believe that these proposed changes will further endanger the lives of all flight attendants and the passengers we work so hard to keep safe and secure.”
How do you know that a pilot might not be convinced to open a cockpit door should one of his flight attendants be threatened to be killed by one of these atackers should he have a knife to her throat. The fact is there are most likely pilots out there that could be convinced to do so.
I would like to think that this could never happen again but I have seen plenty of situations on the news happen where groups of people were so afraid to get involved that they did nothing to render aid in a situation that called for it.
All I can say is I hope you are right.
