Nearly 20 years ago, I was flying Angel Flight trips for people who had to travel for non-emergency medical treatment. These people generally had to travel long distances multiple times per year, and our volunteer flights helped mitigate the expense for them.
An elderly recovering patient from Mayo Clinic asked if he could sit up front in the Baron–and I told hm “Yes.” He showed a lot of interest in the airplane, but always addressed me as “Charlie” instead of “Jim.”
The conversation became even stranger, when he asked “Do you have a drinking problem?” Dumbfounded, I replied “NO!”–and asked him why he asked. He replied–"All the people on the radio seem to know you–but I thought you said your name was Jim–why do they call you “Whiskey Charlie?”
I laughed–and told him that “N22WC was the phonetic pronunciation of the registration number on the airplane!” We had a good laugh over his misunderstanding! (smile)
