BBC News: US to relax airline scissor ban. If scissors are allowed, then knitting needles should be fine, in theory. But I think the second quote is an over-reaction by the flight attendants.
The US is to relax its post-9/11 ban on airline passengers carrying sharp objects, in a move which has alarmed flight attendants and some politicians. Small scissors and similar items will be allowed from 22 December, says transport security chief Kip Hawley.
"When weapons are allowed back on board an aircraft, the pilots will be able to land the plane safely but the aisles will be running with blood," said Corey Caldwell, a spokeswoman for the Association of Flight Attendants.
I fly on December 22nd and I won't have anything sharper than a pencil in my luggage. I'm planning to have the Harvest Moon yarn and a 40 inch size one Addi circular in the checked luggage, and carry some bamboo or wooden needles to work on the Koigu neck scarf while we fly once I'm done with my (as yet undecided but definitely thick) book. It is going to be a very long day.
