An Indianapolis woman was shocked to discover she had been able to board a plane with a three-inch knife in her carry-on bag not once, but twice.
Sara Gallienne had not realised the blade was in her luggage until she got home.
But that hadn’t stopped her successfully carrying it through TSA checkpoints at both Richmond and Providence, Rhode Island.
‘I was going through it (bag), pulled out my headphones and I realised, “Oh crud. I have a knife in here,”‘ Ms Gallienne told WTVR News.
‘I was blown away I could not believe that I had just made it through with this knife. Not one, but two TSA checkpoints,’ she added.
The TSA has seemingly played down the incident saying its greatest focus needs to be on explosives rather than blades.
