UPDATED with photo of United 840 HEAVY after Sydney Kingsford Smith "incident" today
UPDATED - PHOTO FROM STEVE PURVINAS FROM ENGINEERS ON THE TARMAC
I saw two large planes on final approach abort landing - the first of them went on very steep climb with gear still down for quite a while. The second aeroplane aborted about Kurnell.
I watched the main runway stop functioning with a Virgin aeroplane followed by a Cathay Pacific large aeroplane in the taxi queue for take-off just sitting there for about 45 minutes.
I've heard that a United Airlines 747 is dumping fuel at sea, it's holding at about 7000 feet 30 miles offshore.
