The freezing fog sat firmly Bicester over all morning and the viz never really got above 900m ( as measured by standing outside hangar and not beig able to see the far side of the airfield).
Started to drive home - got to Finmere - gin clear - 5 more miles and back into ILS Cat III stuff.
Oh well honours even I got to do lots of flying yesterday. Popham for New Years day next then?
