This morning I just read the first news article on the [partial] release of the study. IMO, the report didn't say what NASA and FAA politicos wanted it to say, so they tried to squelch it. Now the head NASA politico is trying to convince us that the study was flawed in its methodology, so it will inherently cause an inflation of reported incident rates.
The solution, IMO, is simply to release the full report so other independent analysts who want to do so can validate the methodology or show where it is flawed. To keep the full results away from "peer review" will only tend to confirm our suspicions that the politicos have something to hide...
