Do Yanks still really get confused by QNH settings less than 1000 mb? Really? I only few outside the US for 28 years so maybe a bit shocked.
Certainly when the US military started operating from Prestwick during the Kosovo conflict, we were very careful about readbacks of altimeter settings. Right up until I retired 4 years ago, there was still the very occasional prompt needed with C130 crews. My suspicion is that possibly, being ANG , they were more used to flying domestically in the USA - or maybe it was just habit ?
