I was surprised to see some jumbos produced in 1970 are still flying. I only discovered after the recent Kalitta Air freighter broke in halves in Belgium. I would imagine they having undergone an A Test, making sure there is no metallic fatigue on the air frame.

Judging from the sales of the 747-400, I don't anticipate them having a bright future, for the 777s can do its job more efficiently, with lower seat mile cost. Unless drastic measures are made by Boeing to save this Queen of the Skies, technology of other twin engine will take over its crown. As for economy of scale, the A380s have beaten the 747-400.
