What's being scrutinized is not the individual experiences of a bad day for an ExpressJet crew or ground personel; all airlines have problems here and there, every day, in this or that department. There is no airline anywhere that runs perfectly in all departments, at all bases and outstations, 100% of the time. Occasional operational hiccups are a fact of life for even the best-run operation.
What's being scrutinized is that, in a thread about the future of ExpressJet, is people saying "Well, this one time, at this one place, I saw this one thing happen..."
Intentional or no, it encourages the logical fallacy of the "hasty generalization", in which onsey-twosie examples are presented to the exclusion of the operation as a whole, an operation, by the way, which is earmarked by excellent on time statistics, incredibly low operational MX issues, and an increasing contingent of satisfied customers.
Put another way, for every glitch someone goes to great length to delineate, I can give 95+ examples of times when things went perfectly, and more than a few where things went outstandingly. If need be, I can even pull up our performance stats and comments from satisfied customers to back it up. So it's all in where you want to get your evidence from; the singular example, or the overal picture. Educated people know the right answer.
Peace, Ya'll!
