Sometimes, an n of 1 is all that’s needed to justify further study. [Cue the GAMI fanbois: “Nothing has ever been so thoroughly and brilliantly studied before!”]
For one thing, 1 out of how many? Denominators matter. Maybe it’s one out of three, in which case you could say the sample size is too small. That is, more study is needed.
For another, if the 1 is sufficiently serious, it’s worth investigating further. For instance, what if someone filled an airplane with G100UL and the next morning, 8-inch holes were found in both wings, with puddles of molten fiberglass on the ground below? Seems that would justify some caution.
So much of this boils down to George. Raise your hand if you think he’s easy to work with. An image consultant or PR firm, hired five years ago, would’ve paid for itself many times over by now. But his insistence that he alone — the “plucky little company in Ada,” as the av press calls it — has solved the “problem” of lead in AVGAS, his sarcastic social media presence, and his trash talk of the FAA would seem to alienate those people whose agencies he needs to impress. And his recent announcement that “G100UL is ‘commercially available,’” a naked effort to force California to ban 100LL, is a stretch, as far as the consumer is concerned.
