But officially Mantell had chased the planet Venus, metamorphosed later into a Skyhook balloon, and thus, alas, met his death. ...This Venus idea makes it very hard to understand a sighting at White Sands Rocket Testing Ground, New Mexico, where a flying saucer was tracked by radar, and found to be cantering along at a mere 18,000 m.p.h.

A red glow in the clouds over Godman Field, Kentucky—a disk the size of the Pentagon, lurking, silently, above a fighter base—a construction dwarfing the Queen Mary [British ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967: 1,019.4 ft (310.7 m)] supported by dull orange flames that lit up the cloud base and caused Captain Mantell, of the U.S.A.A.F., to be dispatched in his tiny pursuit plane to investigate. When Mantell found it, his voice came over the radio, full of excitement. It was immense, he said, a colossal metallic thing, 500-1,000 feet in diameter, and cruising at 250 m.p.h. He was going to try to overtake it. As soon as it sighted (or sensed) him, the giant began climbing at 400 m.p.h. It accelerated faster than any jet, and Mantell went streaking up in pursuit. The next news of Mantell was that the wreckage of his plane had been found in tiny pieces, scored by peculiar deep lines as if he had got into a shower of some terribly powerful unexplainable something; as though he had flown into the tremendous exhaust stream—or worse—against which no terrestrial metal could survive.

Venus was a machine for making bad weather.

I was like a lost moon — my planet destroyed in some cataclysmic, disaster-movie scenario of desolation — that continued, nevertheless, to circle in a tight little orbit around the empty space left behind, ignoring the laws of gravity.

Those who are skeptical about carbon dioxide greenhouse warming might profitably note the massive greenhouse effect on Venus. No one proposes that Venus's greenhouse effect derives from imprudent Venusians who burned too much coal, drove fuel-inefficient autos, and cut down their forests. My point is different. The climatological history of our planetary neighbor, an otherwise Earthlike planet on which the surface became hot enough to melt tin or lead, is worth considering — especially by those who say that the increasing greenhouse effect on Earth will be self-correcting, that we don't really have to worry about it, or (you can see this in the publications of some groups that call themselves conservative) that the greenhouse effect is a "hoax".

Re the temperature of Venus's surface

No one had expected such a hot Venus

There they go, off to Venus, just for the ride, thinking that they will find a planet like a seer's crystal, in which to read a miraculous future. What they'll find, instead, is the somewhat shopworn image of themselves. Mars is a mirror, not a crystal.

Observation: there was absolutely nothing to see on Venus. Conclusion: it must be covered with life.

"The year 1866 was signalised by a remarkable incident, a mysterious and puzzling phenomenon, which doubtless no one has yet forgotten. Not to mention rumours which agitated the maritime population and excited the public mind, even in the interior of continents, seafaring men were particularly excited. Merchants, common sailors, captains of vessels, skippers, both of Europe and America, naval officers of all countries, and the Governments of several States on the two continents, were deeply interested in the matter. For some time past vessels had been met by "an enormous thing," a long object, spindle-shaped, occasionally phosphorescent, and infinitely larger and more rapid in its movements than a whale. The facts relating to this apparition (entered in various log-books) agreed in most respects as to the shape of the object or creature in question, the untiring rapidity of its movements, its surprising power of locomotion, and the peculiar life with which it seemed endowed. If it was a whale, it surpassed in size all those hitherto classified in science. Taking into consideration the mean of observations made at divers times — rejecting the timid estimate of those who assigned to this object a length of two hundred feet, equally with the exaggerated opinions which set it down as a mile"

What seems to us for us is true.
The planet has no proper light,
And yet when Venus is in view,
No primal star is half so bright.

Venus, it turns out, is broiling hot. There are no swamps, no oil fields, no seltzer oceans. With insufficient data, it is easy to go wrong.

The real significance of Magellan's voyage was not that it was the first to circumnavigate the planet, but that it was the first to realize just how big that planet was.

Two airline pilots, Adams and Anderson, were flying their D.C.3 the 130 miles from Memphis to Little Rock on the night of 31 March 1950 when a huge glowing flying saucer zoomed down at terrific speed to investigate them. On the central cupola there was a bright blue-white flashing light—either a signal or part of the propelling mechanism. And on the lower side, the airline pilots observed a row of eight or ten brilliantly lighted portholes. They thought they were portholes, but admitted that they could have been vents through which some kind of powerful energy was flowing.

Nine flying saucers, in loose formation, were seen by Captain E. Smith, of United Airlines, eight minutes flying time away from Boise, Idaho, on 4 July 1947. Smith and his copilot, Ralph Stevens, saw the disks silhouetted against the late-evening sky, and at first thought they were aircraft. Notice, please, that they were ‘silhouetted’. Fireballs, illusions, and refractions of light do not produce dark silhouettes against the evening, or any other, sky. Four more saucers joined the group, giving the two pilots and their stewardess time to observe them thoroughly.
