Longreach - I believe Longreach is the generic name given to all QF 747-400's, just as SIA called their first 747-300's "Big Top ". and their -400's Mega Top. QF delivered their first - 400 non-stop LHR - SYD which is a long reach. Min crew, no baggage - not even theirs I believe ! - and re-flightplanning in flight to reduce the contingency required stage by stage. Good effort. ( Sorry if the memory has made a few errors - happy to be corrected )
