Gentlemen
Thank you very much for your interesting and informative replies. yes of course it was 09L don't know what iwas thinking of there. It struck me as i said what a nifty bit of and hoc controlling that was to get the three inbounds from the north delayed time wise but beautifully sequenced back for the ILS as the picture from FR24 shows exactly what i saw from a different perspective. And as one response says -all in a days work is being too modest because clearly it doesn't happen every day and it really was very impressive to see.
I agree with HD that FR 24 is a bit dubious near the ground - I was using it yesterday to see what was actually heading for finals from the north rather than this incident.
thanks again and a big well done to the controller-by the way HD would that have been the Heathrow Director handling these flights given the location?
