One of the biggest complaints concerning the UFO world is the tenuous data. There is no repeatability. There are rarely ever any follow up work and further testing. Lots of people have had these kinds of materials, but they often get lost, or "confiscated", and who knows. You know, real stuff that could remove doubt as to origin. Something always gets in the way.
The only problem I see here is that it seems a bit premature. I mean why wouldn't they wait, do the additional testing, and come to the UFO world with something conclusive, ... like a piece of metal from outer space?? Instead it's another case where, we need to do more tests. It could be a mistake. But let's all get excited because it looks like something solid. What could go wrong?? Hopefully we'll hear more soon as the testing is to be done soon right?? As much as I've seen and read it's hard to hold my breath anymore because nothing definitive ever seems to surface. Hopefully I'm wrong on this one.
