Longwood Warren 1995: a cometary "disapparition" predicted before the fact.
A now-famous crop picture which appeared at Longwood Warren on June 26, 1995 showed a schematic picture of our inner Solar System, but with planet Earth missing:
Yet three other planets (Mercury, Venus and Mars) were drawn so as to match their approximate locations only one month later (David Pinnegar, www.hammerwood.mistral.co.uk/halebopp.htm):
Some authors have suggested an "apocalyptic" interpretation for this particular crop picture, as if the whole planet Earth might "go missing" in the near future!
More plausibly, Longwood Warren may have been referring to the "disappearance" or break-up of a comet which was then approaching Earth, namely "73P/Schwassman-Wachmann 3". By late August 1995, astronomers saw that it had unexpectedly begun to break up, as icy comets sometimes do when they approach the heat of the Sun.
"In 1995, comet 73P/Schwassmann-Wachmann 3 did something unexpected: it fell apart. For no apparent reason, the comet's nucleus split into three minicomets flying through space. Astronomers watched with interest, but the view was blurry even through large telescopes."
Perhaps that break-up began somewhat earlier in July, as indicated by the crop picture? But during July and early August, the comet could not be seen clearly through Earth-based telescopes, because it was still in the glare of the Sun.
In any case, we can now see easily that the meaning of Longwood Warren was as follows:
"Approximately one month from now in July 1995, an astronomical object (or comet) that is currently in the vicinity of Earth will begin to break up or disappear."
Indeed, astronomers describe the periodic sighting of any comet as an "apparition". So when a comet doesn't show, but breaks into many smaller pieces, what else should they call it except a "disapparition"?
It is no real surprise that comet 73P/Schwassmann-Wachmann 3 broke up or "disappeared" as it approached both Earth and Sun. Comets tend to do such things, very unpredictably.
The true surprise was that those unseen "crop artists", who drew Longwood Warren in June 1995, seemingly knew that comet 73P / Schwassman-Wachmann 3 was going to break up, two or three months before any astronomer on Earth had made such a surprising discovery!
Certain crop pictures from 1994 illustrated details of the Shoemaker-Levy comet impact with Jupiter, yet none appeared clearly "before the fact" (Kris Sherwood, www.cropcircleanswers.com/Angel_ForeTold.htm).
Other more recent crop pictures (e.g. Wayland's Smithy 2005 or Etchilhampton 2006) have suggested that "something astronomical" will occur in August 2007, but we have to wait another nine months to find out for sure.
By accurately predicting such "unexpected" astronomical events "before the fact", the crop artists seem to be demonstrating (over and over again) that they possess the technological means to do so: namely time-travel technology, as illustrated also by five "wormhole" pictures from the summer of 2006.
What would be the philosophy of a race for whom time travel is a reality? And might these "predictive" crop pictures, which could not plausibly be made by Earth humans, be a prelude to open contact?
