The Transportation Safety Administration has come up with one of the goofiest ideas yet in this post-9/11 era of commercial air travel.

It says it plans to allow airplane passengers to pack blades when they fly.

And to no one’s surprise, flight attendants and pilots – pardon the pun – are up in the air about it. They think it’s a nutty idea; they believe it invites tragedy; they’re going to lobby TSA vigorously to take back this cockamamie proposal.

Maybe it should be no shock at all, given TSA’s occasionally awkward enforcement of rules designed to make air travel safer. It has allowed their air terminal agents to frisk old women and babies while looking for bombs, although one can argue that dedicated terrorists think nothing of planting bombs on the very young and very old.

Whatever. TSA brass seems to have forgotten that the 9/11 madmen walked aboard those commercial jetliners nearly a dozen years ago armed with box cutters, which they used to cut the throats of flight crew members before flying the aircraft into buildings – and ushering the United States into a new era of international warfare.

I cannot think of a crazier idea than this, short of letting passengers pack firearms or allowing them to engage in in-flight cellphone conversations on trans-oceanic trips.

I’m with the flight crew members on this one. They have a difficult enough job as it is. Why make it potentially impossible when passengers are armed with weapons?

Crazy …
