Over the Poles Flight
I had a question, and I would like to know if you could help me.
....back in October 1977, Pan Am flight 50 flew from SFO to LWT to CPT to AUCKLAND and back to SFO
They did it in 54 hours and 7 minutes.
If that flight on the same route, over both Poles, was to take place today, on a commercial airliner, which aircraft would be the most efficient to do it, and, could it make in less time?
Thank you very much
Jose

On the 747-400, if you left the Mag/True switch in Mag, the display switched over to true automatically at around 80 North while heading north, and then switched back to Mag when you got back down to around 80 North on the southbound leg.
