Deplane,,wait for the aircraft to be cleaned, serviced and reprovisioned - usually three hours in transit, then back on for a one hour Melbourne flight
Sunfish is writing unmitigated nonsense! I don't know if he's trying to be deceptive by re-writing history or if old age is catching up with him.
QF2 operated from LHR via various routings to SIN, thence SYD and terminated in MEL. Scheduled arrival time in Sydney was 0620 local while its scheduled departure time for MEL was 0800 local. By my calculation, this is a transit of
1 hr 40 mins which is substantially less than the three hours Sunfish suggests. Not only that, if the flight was late arriving into SYD, the QF standard required a transit of something like 70 minutes or whatever required to meet the 0800 departure time.
I will say no more other than to suggest Sunfish (1) re-reads the post of Aerial Perspective, and (2) have a Bex, a cup of tea and a good lie down!
