The idea of UFOs being alien spececraft does not stand up to any
kind of logical scrutiny.

What logical scrutiny? It's only logical in the context of the
absence of evidence to call such scrutiny "logical". e.g. believing
in Santa Clause can be quite logical for a child until he/she
realises that a big fat old man would have some physical difficulty
coming down the average chimney and many modern homes no longer have
chimneys. So the factual evidence then dispels the myth. It's never
logical to come to a conclusion based on limited evidence. It is
more logical to keep an open mind in regard to the possibility that
some UFOs are of ET origin, particularly since what we actually know
about the universe we live in is infinitesimal and a Trillion stars
bear witness to that fact, we don't even know about all the bodies
in our own Solar system. --

You can't say that UFOs come from one source.
Because the evidence/information says otherwise.

ie.
UFOs can be divided into 3 main sources ...

1. Extraterrestrial - ie. visitors from outer space or other
   dimensions.
   ie. Physical and non-physical dimensions

2. Terrestrial
   eg. from US Government secret projects or 'black budget'
       sources.
       from Nazi Flying Saucer technology (Note: this is of
       a specific UFO type).
       Any other possible earth built origin?

3. Other - This would be the category of mistaken identity
   of normal aircraft seen at unusual angles to be mistaken
   for a 'UFO' or that of astronomical sightings mistaken
   for a UFO, however if the object shows the abnormal
   characteristics of a UFO (very high speed and erratic
   maneuvers) then it would be of 1. or 2. above.

Exterrrestrial UFOs tend to fall into specific UFO types,
such as the beamship and wedding cake designs photographed by
Billy Meier - and others...

I agree but there is also

4. Fake UFOs. People do fake up UFO images and claim to be in contact with
Aliens, there are charlatans about. Persoanally I would place Billy Meier in
that catogory.
