Why Classical Astrology works?

Traditional Astrology  was essentially practical. Astrologers read the message of the skies to know about EVENTS, facts. The winner of some war, the future of a kingdom or the destiny of a ship lost in the dangerous seas were the big questions. People wanted to know practical things concerning real life.
However in the XVII and XIX Century, materialism prevailed ideologically, and the World was seen
as a complex mechanism which men were sooner or later put under their absolute control since destiny and fate, were now consider old superstitions. This was the era of the "free will".
That is why classical, predictive astrology became psychology. The old malefic planets Mars and Saturn were now "teachers". The red planet didn't revealed the winner of a battle but the level of "spiritual energy" available for the client.
Saturn now is not a malefic but teaches us "prudence" or the virtues of moderation.
The great old Astrology of masters like William Lilly became a pale pseudo-psychological mumbo-jumbo whose only purpose was to make the consultant happy. Victorians didn't want to know about events or the future, so the new astrologer just told these clients what they wanted to listen...(All the fairy tales must have a happy ending.)
The traditional rules of the science and art of astrology were deliberately forgotten and denied.
The astrological experience of  thousands of years became a concoction of psychoanalysis and New Age.
But some astrologers said NO to this decadence and went back to the lost secrets and rules.
Classical, traditional astrology works because is the authentic Astrology, the millenary art and science of the Stars, and not wishful thinking

Astrology on Kenneth Arnold UFO Sightings

Kenneth Arnold UFO sightings on June 24 1947 can be seen as the Natal Horoscope of the so called Flying Saucers.
On June 24 1947, Arnold saw some unidentified flying objects  seen nine unusual objects flying in a chain near Mount Rainier, Washington at 3 PM.   ( Long 121.40,  Lat. 46.44)
Let us analyze the astrological chart of this important ufological event. In classical Astrology, the ruler of the Chart, with rising sign in Scorpio is Mars, so the intentions of the flying saucers is not benign because Mars rules war, violence and invasion. Worst, Mars at 25,36' of Taurus conjuncts Algol,  the most unfortunate, violent, and dangerous star in the heavens. By the way, is the star of "loosing our head". 
The lesser malefic Mars is in the cusp of the eight house of death. 
The red planet is opposite to Jupiter, (benefic) and in sextile with Mercury, the planet that rules communication. The sextile means that the opportunity of communication between the ufonauts exists, but with martian purposes which are not benefic. (Think in the abductions.)
Uranus also in the Eight House tells us that the motivations of the ufonauts are contradictory and dictated by the aliens interests.  Sun, Saturn and Pluto in the nine house confirm that these entities come from some distant planet or dimension, but Saturn is the big malefic. 
In the eleven hose of purpose and projects Neptune tells us that the ufonauts are not interested in friendly contacts but will keep their secrets.
But here we have something curious and promissory. In charts of wars and invasions, Jupiter in the first house implies that in the end we will win.  Also Saturn in the Nine and Mars between seven and eight show that the hostile plan of the aliens will fail. Moon's in Virgo, in the eleventh house, applies for a trine to Part of Fortune. This suggests we will find unknown but powerful  allies. 
Something else. The rising angle, cusp of the First House, is in the Via Combusta, and this means that events take a sudden, unpredictable turn.
