In the last few weeks, I have heard someone playing around with an aircraft band radio on the emergency frequency of 121.5000. A few minutes ago for example I heard someone say "Hey! Hey! Hey!" then silence. This is not the first time it's happened. The most surprising thing I have heard was two weeks ago when I heard "This is the captain speaking, I want you to know that I am wearing nothing except my cap." Obviously it's someone's idea of a joke but I imagine the perpetrator could get in real trouble with the FAA if caught. I live in NW Arkansas BTW.
