Last week I flew from Boston to Chicago with a Streamlight PT 1AA in my pocket. The only issue I had is then the agent took it out of the plastic bowl where I put all my change, sunglasses and watch in. She picked it up and asked me "What's this for?". I couldn't help myself when I said "So I can see in the dark." She gave me a dirty look, fumbled with it for a moment, clicked the tailcap, and strobe-ed herself in the face. I couldn't stop laughing as she dropped it back in the bowl (still on) and turned back to telling an old woman to get out of her wheel chair so she could be body scanned. I noticed the agent kept blinking alot after that......
