PABs (Precision Aneroid Barometers) are in every military tower I've ever worked at, though I left the mil in 2001.
Oh I am disappointed! No mahogany?
I am a bit biased against people who work in Control Towers as two of them nearly killed me! See threads on Mid Airs etc.......................
To get back to QFE/QNH - they both have their place properly applied by intelligent operators.
