The people in the report I referred to didn't claim the UFOs were space aliens. They simply reported what they saw.
That doesn't stop people who make television programs from heavily implying that those witnesses "must" have seen alien spacecraft. As I suggested, I don't generally have a problem with the witnesses themselves in general, but with those who want to read into the testimony presumptions and conclusions that just aren't there.
Shows like the drivel that's being shown on "science" channels put the cart before the horse. They try to present sightings as evidence that space aliens exist and are visiting Earth. That puts the interpretation of the sighting as a premise instead of a conclusion, making the whole thing circular.
While they pretend to analyze and discuss the evidence, the alien spaceship hypothesis is always on the table -- for no readily apparent reason other than it's a bit more scientifically plausible than fairies or demons. There certainly isn't any more evidence for aliens than for fairies and demons.
I think it's important to differentiate people who automatically equate UFOs with Reptiloids from Alpha Draconis from folks who report something unidentifiable ... and leave it at that. 
I agree. That's what I believe I'm trying to do. Orion437 seems to think Prof. Hawking lumps them all together. I interpret Hawking's statement as making a distinction.
