Art Bell had a real JPL scientist on recently. Bell opened the door to let the JPL scientist argue against some of Hoagland's theories.
It was surprising to hear him just say something to the effect of "I don't see it, but I would not want to deny that someone else might have," or words to that effect.
It made the JPL scientist sound that much more credible (and generous) that he would not discount another's opinion, even when indirectly invited to do so.
A broken clock is right twice a day.
Well, Hoaglands made a big deal about the "robot head" on the moon. I don't see it either. I emailed George when Hoagland was on and basically said "If we took 100 sewing machines and dropped them on Mars 100,000 years ago, we would find them in various shapes. Some totally eroded and unrecognizable. Some almost pristine. Most would be broken and corroded, but the various parts would be laying around."
You wouldn't find a needle here. Then a wheel a quarter mile away. Then a spool of thread at the other side of the crater sort of thing.
OTOH, I do agree that it's at least POSSIBLE that NASA amd the military are covering things up. There was some fellow in England who got convicted of hacking into JPL's computers.
He basically said he found lots of evidence of SOME PEOPLE at JPL who's sole purpose in life was to tamper and airbrush photos, and that if we knew the truth, we'd be astounded.
The real scientists that Bell and Noory have on always seem to be briefed to treat all the callers as if they are intelligent and are asking intelligent questions about possible things. The exchanges can be pretty ludicrous.
