Looser regulations from the Transport Security Administration have many families of 9/11 victims upset; knives are now permitted on flights.
The new regulations allow knives no longer than 2.36 inches in length to be carried on flights. The blade must also be no wider than six centimeters. Souvenir bats, golf clubs and other previously banned equipment will now be allowed as well.

In a CBS News article Stacy Martin, president of the Southwest Airlines Flight Attendants Union, said he’s surprised, especially since box cutters were used by terrorists to hijack the planes involved in 9/11.
“When you look back before 9/11, all it took was box cutters coming through,” Martin said. “At this point you have knives, small knives, it’s all the same to us … They’re allowing these items to come through and they’re putting the responsibility of the cabin completely on us even though they know coming through security are these items.”
Knives will be allowed on flights starting April 23. For more information, go to CBSnews.com
