Qantas A380 out of Heathrow earlier with an "ASY" callsign, presume relief flight to Tel Aviv.
I did see the Qantas 380 heading off (hard to miss as it's so conspicuous) and idly thought "that's going off early" and carried on with my morning. Is there any more info since yesterday ? Quite rare for a LHR departing civvy to have a mil flight number.
