I am not (like most of us here) an aircraft engineer or an airline expert, or a pilot or crew member, but allow me to comment:
I often see that many people keep saying how they miss the Tristars or the B 727, and they hope that airlines will keep them flying.
On the other hand I see many people are saying how bad the DC-10 or the MD-11 etc is and that they would prefer a 777 instead.
"People kill their horses when they get old" and they tend to forget how these aircrafts served for yeras, and also under what circumstances they were produced.
I spare the valuable space in this site to comment on which aircraft is the worst ever built..........
What about Wright's Plane?
Terrible design, safety record and comfort level..... wasn't it????????????
