Just checked my logbook and I have a note that it was 942 on 20th Dec 1982. We were all talking to Highland Radar working out what to do and settled on us all setting 950 to keep our seperation; up comes Nigel flying a Budgie down from SUM to ABZ an informs us plebs that he can set 600 or something stupid. I remember the day well and the 45 degree drift not being apparent until we saw SHD lighthouse appear in the 10 o'clock while tracking towards it.
Tell the young wippersnappers of our warstories and they get all glazy eyes - dammned impertinance.
