You say that this have debunked anything, maybe not on its own but it is just another piece of their evidence being shown to be either a mistaken observation or erroneous conclusion.The burden of proof is on those making the claim. If SUFON and the witness are claiming a crashed interdimensional craft left high levels of radiation behind they should present evidence that she's y this to be true. If you now show that there was an error in their method of collecting evidence and that the was only normal background radiation levels then it makes their claim invalid. I accept they have presented other evidence, such as their sightings of lights in the sky, Surveillance aircraft overhead, soldiers on the ground, VIP aeroplanes at a nearby airport, and high EMF levels. However, just about all of the evidence they have used for the military presence being part of an a UFO ambush and recovery has been thoroughly explained by the planned and published special forces parachuting Exercise with flares and a nearby drop zone. The other weird things that they say happened, like 'it was snowing up a Welsh Mountain in be February' and 'there were trees fallen in the forest' don't seem that weird to me at all. So all we're really left with is the High EMF levels. I am interested to hear of their method, and the control data they are going to take away from the alleged crash site. As you said, the witnesses do seem to be very open with their evidence and methodology, I have never thought that they have been deceitful or dishonest in their statements, just that they are mistaken.
i understand that SUFON and the witness will be publishing photos of the 'craft' in the coming days. Can't wait to see them. Hopefully they will conclusively show how wrong I have been, but to be honest I'm just expecting a picture of some lights in the sky.
