The female passenger was checking her carry-on luggage when she observed that she was carrying a Swiss army knife with a 1 1/2 inch blade and another knife with a 2 1/2 inch blade, Davis said. The crew was made aware of the knives and turned the plane around.

Hmmm ... TSA missed the knives, the passenger that had the knives notified the crew that she had them when she realized it and they still had to turn the plane around and go through a bunch of theatre even though the knives didn't actually pose any risk.
