Even other UFOlogists, who don't neccessarily subscribe to the so-called 'nuts'n'bolts ETH, have expressed similar opinions to skeptics, regarding the ETH Ufologist approach to investigation-
From MAGONIA Monthly Supplement No. 22 December 1999

To turn a bolide into a flying saucer requires a special technique, which was quickly developed by ufologists. This can be summarised as a list of rules:
(1) Avoid consulting astronomers, amateur or professional, concerning a particular case. They might spoil it by giving details such as the direction and speed of the object, and even an estimate of the orbit it was following before hitting the Earth.
(2) Be sure to quote those witnesses who say that it passed over their houses at rooftop height.
(3) Look for witnesses who say that that the object hovered for a time, or changed direction. One witness is enough. Be careful not to mention that hundreds of other witnesses failed to notice these strange manoeuvres.
(4) Assert that the object could not have been a meteor because of its flat trajectory and long duration.
(5) Critics who disagree with your findings should be labelled as "sceptics", "debunkers" or "armchair ufologists".
The above treatment of reports of bolides by ufologists can not only be found in the earliest writings on the subject, but it also continues to this day. It can be ascribed to ignorance or to intellectual dishonesty. The origins of this style of ufology can be traced back to Donald Keyhoe, who took full advantage of the fact that some senior US Air Force officers thought that the UFOs could be alien spacecraft.
It's worth following the link and reading the article before going into attack mode.

Hey NigelTM,
If you look at some of those reports the witnesses usually didn't describe propellers, the sightings (not the known Hoaxes of the time) are typically indistinguishable from modern day sightings. Sightings also date back much further at least several hundred years, these again are basically indistinguishable from modern day sightings.
Indeed, some of them are the classic lights in the sky, others are cigars, discs and spheres. And others are just plain weird, like these two from the MAGONIA database (

Jul., 1868 Copiago (Chile). A strange "aerial construction"
bearing lights and making engine noises flew low
over this town. Local people also described it as a
giant bird covered with large scales producing a me-
tallic noise. Although not an actual landing, this is
the first instance of close observation of an unknown
object at low altitude in the nineteenth century.
(Fort 638; Anatomy 11)
1880 Aldershot (Great Britain). A strange being dressed in
tight-fitting clothes and shining helmet soared over
the heads of two sentries, who fired without result.
The apparition stunned them with something de-
scribed as "blue fire." (FSR 61, 3; Magonia)

We have to take a closer look at Project Blue Book files. Many of those explanined files are seriously flawed and there have been reports of some UFOs leaving behind trails.
We should be taking a closer look at Project Blue Book and those explained files.
My favorite is Project Blue Book's explanation that a propeller-driven DC-6 was the UFO that was flying circles around and trailing an RB-47 jet bomber for 1 1/2 hours over several states, which was also cruising far above the airspeed and altitude limitations of an DC-6
But were Blue Book's explanations meant to debunk the phenomena or provide a calming explanation?
Remember that the evidence indicates that in the early years of the modern UFO phenomena, ordinary people tended to either believe that the phenomena was connected with US or Soviet 'secret' weapons, or didn't believe at all.
Likewise the Cold War tension was quickly building up. So what may have seemed ridiculous from a modern/critical point of view, probably was the preferable to providing no answer at all.
After all these were people of a similar mindset to those who were advocating the teaching of duck and cover drills in schools, should the reds decided to send some nukes stateside.
Seriously all one has to do is look at the devestation unleashed on Hiroshima and Nagasaki (and later the footage of the tests against buildings and vehicles) to realise that hiding under your desk isn't going to do much if a strike lands in the immediate vicinity of your building...
So they go from calming explanations, to no scientific value or threat. And the government has no desire to re-examine those old cases, since they've been beuracratically stamped 'case closed'. Add to that the political perception that the voting public would view this as a frivillous waste of tax dollars...
So we're left with calming explanations and FOI (if anyone has the time, inclination and resources to go through all those old cases).
