Lighttown,
A one off (we hope) chance for some interesting experiences and RULES and JOBs WORTH get in the way .
Utter rubbish.
Whilst I of course do not doubt the veracity of the above reported overheard TB10 conversation, leaving aside the issue of currently being unable to offer IFR (or apparently SVFR) clearances, take note of the following NOTAM regarding EGLL...
Q) EGTT/QFALC/IV/NBO/A/000/999/5129N00028W005
B) FROM: 10/04/16 20:26C) TO: 10/04/17 12:00
E) IN LINE WITH CURRENT UK AIRSPACE RESTRICTIONS
AD IS CLOSED
... and which is likely to be reissued as long as the effective airspace closures are in effect.
EGLL ATC procedures do not allow them to position traffic to a closed runway, which the runway surely is when the airfield is closed.
So, airspace clearance issues and the airfield itself is NOTAMed closed, maybe it's time to stop the pie in the sky let's go do touch and gos at Heathrow posts here and elsewhere.
