One night I was flying a 172 in the standard VFR sightseeing circuit for Niagara Falls. You know, low for rotary, higher for fixed wing, further out the faster you are.
Bright landing light appeared to lap me. In the darkness thought it might be a King Air or something. Asked over area frequency. what type are you?'
Reply came back with alarms going off in the background, we're an A320.
I got out of there pretty quickly!
