In defense of DIA and the designers (of which I was not one; the job I worked on is still in design at the moment), the original runway and apron problems seen at DIA were contractor and materials related, not design related. They got blamed on design by a couple college professors that were basing all of their opinions on theory, and had not once been involved with any of the design, decision making, and didn't technically know what they were talking about.

But back to the Calmini SAS (which I have yet to make any negative design comments on, for the record), what are the latest testing notes/results on it?
