20 years ago this month, Gil and I were boarding our first flight to Tanzania.

As we went through security, my carry-on bag got pulled aside. I watched patiently as the agent unzipped my black roller bag, poked around, and pulled out a full-sized pair of Fiskars scissors.

I was mortified. “I’m so sorry,” I fumbled. “I was using those for cutting tape for boxes and I meant to take them out before we left for the airport. You can confiscate them.”

He shrugged, put the scissors back into my bag, and waved me through. 

I was taken aback. I recall telling Gil, “Fiskars scissors are really sharp. I’m surprised they are allowing me to take them on the plane.”

I don’t remember anything else about that journey. But that memory stayed with me because it was just a few weeks later when 19 terrorists with knives about as big as my scissors forever changed air travel, America, and the world.
