NEMO ?
During my C.B period I had to decide on a 'handle'. For some unknown reason I thought of the Darky procedure, Hello Darky, Hello Darky, This is Nemo, this is Nemo, this is Nemo over. We did not use any call signs, letters of the day, or aircraft identity numbers just Nemo, and remained 'unknown'. On joining PPrUNE , what better than cliffunknown. However since then this fool has 'blown his cover'.
