Advocatus diaboli
I understand where you're coming from, but - believe me - "real world" perspectives from operating aircrew based upon actual experience of flying these aircraft in service can be hugely valuable to those of us who have to make, or can influence, aircraft type selection decisions. The marketing communities of the manufacturers put up such a barrage of b/s that quite serious performance, reliability or maintainability issues can sometimes fail to become known in the public domain.
For my money, if you've got any opinion about heavy jet transport aircraft based upon experience, keep on posting!
