I've just come across this article in the Sunday Mercury via the UFO Chronicles website. I have to say it makes interesting reading insofar as although there is nothing new being brought to the table so to speak. The author of the article (unless I'm mistaken of course) does appear to have sourced some of his information on line!
While another source quoted in the article comes from author Peter McCue. Whose latest publication "Zones of Strangeness: An Examination of Paranormal and UFO Hot Spots" includes the alleged crash near Penkridge back in 1964 and is available to purchase from Amazon:
Everything aside though, the exposure afforded both from the Sunday Mercury, the UFO Chronicles and last but not least Peter McCue's latest publication. All combined together will hopefully offer a new lease of life to an otherwise cold case.
