Well, we arrived at 8:00 this morning after 13 hours in the air between L.A. and Sydney.  We were travelling at 580 mph at an altitude of 36 000 feet.  The outside temperature was as low as -60 F. It is hard to fatham that speed and it was a very smooth ride.  We did a little site seeing today. We went to the harbour and will do more site seeing tomorrow, the Opera House and more of the harbour.  We have been up now for 43 hours. We are all dead. We are planning an early night and then head out again in the morning. I will upload pictures tomorrow. G'day to all.
