It's in QR's
Well it was in QR's last time I looked.
And it was never just GR.1 or F.3
It said in the great book of rules
Aircraft Name : 'Harrier'
Type : GR
Mark number : Mark 1
Harrier GR Mark 1
of course the military love to abbreviate things to the point of being meaningless at times.
I recall a 'driver of Tornadoes' telling me that he flew 'GR 1's'
to which I asked if he meant Jaguars or Harriers? (I was making a point)
The poor soul just stared at me and repeated "GR.1's" as if the multi-nation wonder-bomber was the only creation to thus named.
I fear as the service has shrunk, so has its collective sense of history, tradition and even understanding of who we actually are.
And with it our ability to apply QR's to the naming convention of our aircraft.
