TSA knife rule: would an airborne fistfight been worse? Posted at 08:00 AM ET, 05/08/2013 (Andrew Harrer/Bloomberg News) Seems a serious fistfight broke out in the first-class section of an American Airlines flight from San Antonio to Dallas-Fort Worth last week. "They were actually throwing punches," Army Brig. Gen. Jason T. Evans told a local television reporter. "It was actually a fight," he said, according to the station's Web site, WFAA.com Evans and a couple of other passengers stepped in to break it up. But it appears some punches landed - one of the men had blood on his face and shirt - but the extent of injuries couldn't be determined. Might have been worse if they'd pulled out their knives, but of course knives aren't allowed on airplanes . . . for now. Other changes could include allowing golf clubs and ski poles and such on board. And now the chatter is that TSA may decide to put them into effect over the Memorial Day weekend, which begins May 24. The TSA had asked for public comments on the changes, and agency officials are apparently going to brief folks on the Hill later this month.
