I did rather have a mental image of a Rab C Nesbit soundalike in a bit of a "Ha' a drink wi' me, pal?" state of mind.....
How's the head today, m_J?
Times have changed at Brize now - for the better! Many years ago I took off from Benson to climb to FL100 for some hi-rot spinning - and the only clear patch was north of Brize. Well to the south of them, I gave them a courtesy call to advise that I was passing FL45 and would be climbing to FL100 through their overhead, remaining outside the CTR. Whereupon some rancid crone told me "Not above FL60!" in a 'nanny knows best' voice. So I repeated my call and she snapped back with the same 'instruction'.
"Well, I tried to be helpful. Anyway, I
will be climbing FL100 and I
will be remaining outside the CTR. Squawking 7000, changing to en-route, good-day....click!".
Then a little devil on my shoulder turned Mode C off until I was clear of their overhead....
Childish? Yes - but it made the point!
