I was surprised to see this ad:
Here’s how things looked back in 1968:
And here’s how things looked back in 2008 for Boeing’s jumbo jet competition, the Airbus A380.
Where’s our jumbo jet scorecard?
Boeing 747 1st Generation = SUCCESS! Unquestionably, but now obsolete
Boeing 747 2nd Generation = SUCCESS! Unquestionably, but pretty much obsolete
Airbus A380 1st Generation = FAILURE! Pretty much. A big money pit for Airbus
Boeing 747 3rd Generation = FAILURE! Approaching obsolescence faster than expected
See a pattern here?
