Everyone of your points (which are true and an issue)have more to do with profitability and usage rates of the operator and very little to do with flying-customer issues - except the DRR one. But again, most DRR issues have to do with operators and not the manufacturer. The MD11 had enough issues, as you pointed out, without having the additional burden of poor operator interior installations and shoddy maintenance added to its record. And that was what I was reacting to.
It was truly sad that American, which had one of the largest (and loudest) pilot-driven design inputs of any operator on the MD11 Launch Team, undercut its team by badmouthing the plane prior to delivery. When EIS occurred, it was an uphill climb to overcome the stigma and closed minds. Sadly, the pilots were getting the lesser bugs worked out when American shut the model down.
Remember when AA dumped the 11? They went to that joke of an airline USAfrica, which was a disaster waiting to happen.
I was a pax only once on an MD-11, Swiss Air (not the follow along, Swiss, who just got bought out by Lufthansa), LAX to Zurich, we sat on the ground for 4 hours (center seat!) tackling hydraulic issues before take off.
Nasty.
