I only scanned the article, however it seemed to miss the fact that (according to the late Joe Sutter, who was responsible for the747 design) double deck airliners suffered from a lack of cargo space for the number of peeps aboard, among other major issues. And, there were many double deck aficionados that had to be "won over" at the time.

The Boeing managers who chose to not go double decker were standing on Joe Sutter's incisive and brave shoulders.

Sounds like a fitting subject for the sequel to “You Can’t Order Change: Lessons from Jim McNerney’s Turnaround at Boeing”. :^)

I’ve never boarded one, but have seen ‘em up close, they seem enormous. Probably a nice smooth ride, particularly compared with the old “Ruptured Duck” prop jets across Lake Michigan, flying into Grand Rapids.
