That pilot certainly wasn't sticking to standard phraseology there was he! It must be gut-wrenching to be sitting on the other end of the radio and receiving a mayday call like that. The pilot is in IMC, has lost control of the aircraft and is panicking and all you can do is talk calmly and hope that he gets it together. Very well handled though, especially as it is a FSS - aren't they normally for weather briefing and flight planning etc?
