blackace;
I suspect every professional pilot on this forum will grant the respect engineers rightly deserve - it is upon the engineering professions' knowledge and expert skills and experience that we rest our substantial trust and we hope that they all got good marks at university!
I don't think it's the "workability" of the design but the infrastructure design in which work must be done, the "people management" aspect, and, frankly, trying to do a huge and complex job under-resourced: on-the-cheap. One can have a mausoleum, a monument-to-ego such as Toronto's Terminal One which Lou Terpen built, for whom we do not know, or you can have a run-o'-the-mill terminal which does not yet look like yet another ugly shopping mall and is actually an airport terminal - it is the design and subsequent management of resources and appropriate services for passengers which separates outright hatred of airline flying from mere strained tolerance. People will put up with a great deal if they know their needs are being respected and cared for even if it falls short. Many arrangements however, virtually shout disrespect for the traveller and it is that diffidence towards the very sources of revenue which makes such mausoleums and what-have-you's possible, that is making people actually consider POSH again...
