I did see the take-off this morning just after 07:00, from the upwind end of 27L near Stanwell. It was pretty majestic and stable, despite the gusty conditions. It was also remarkably quiet in the climb, no different from the A319s/320s etc. that preceded it. Incidentally, it was about the 16th departure this morning from start of play, and all bar one were Airbuses of various types - quiet something.
