I have read various accounts in books and the internet as to which came first QNH or Question/Query Newlyn Height.
By this I mean is QNH an acronym or is Question Newlyn Height a useful pneumonic for QNH.
If anyone knows the answer please tell me.
This could all be a load of tosh, but never heard a better explanation or had it dissproved.

The mnemonic for the code is "Query Newlyn Harbour". Newlyn Harbour in Cornwall, UK is home to the National Tidal and Sea Level Facility which is a reference for mean sea level. Another mnemonic sometimes used is "Q - Not Here" meaning it refers to the pressure setting that applies away from the airfield. This is to distinguish it from QFE, which novices sometimes confuse.
