Thank you,
Bevo ... that could have been me at
either London or Eastern
"Cleared to the Lakenheath fix, decent and report level FL180, expect penetration on arrival, base weather <blah blah blah>"
PS: I was the Staff Officer who persuaded USAF and others to use the Colour Code for weather, saving a lot of RT time
PPS: I used to visit LK [and UH, and BW/WB] regularly to lecture at the Instrument School Indoctrination for new USAF pilots in the UK. Indeed, I still have copies of the presentation slides!
PPPS: I have a former USN pilot buddy in VA, who regularly flew from Rota to ML around that time. We reckon we spoke often before we met in a neighbourhood bar a few decades later ... and I will be seeing him there again in a couple of weeks
