The next generation 747 shouldn't be an issue; it's built around a well established airframe.
I found it funny how each airline gives the 747 its own personality. Pan Am was the best. Loved the Clippers.
South African Airlines was the second best, they trying to be propa like the English. Heathrow to Jo-Berg was always a hoot on SAA.
I am thinking the competition is good.
Retired, I hardly fly anymore. Such a shame. There is no greater experience in the world if you pay attention and don't go to sleep when there is daylight.
