Exactly. Pilots are highly trained, but they are not experts in everything (physics, atmospheric science). At the end of the day, everyone is fallible -- and even the experts are sometimes surprised. These reports can only be treated as best efforts to fit observed phenomena into an existing framework of (inherently limited) understanding. When the phenomenon is adequately oddball, you have to expect an increased level of misinterpretation. See also: doctors, scientists, infosec practitioners, ... Clearly, this is adequate justification for collection of additional data, but it's not enough to draw conclusions from.
