This is Volume 2 of the Ministry of Defence report 'Unidentified Aerial Phenomena in the UK Air Defence Region', Defence Intelligence Staff Scientific and Technical Memorandum 55/2/00, dated February 2000 and received 7 December 2000. It gathers 25 working papers on natural and man-made phenomena, meant as a reference for analysing UAP reports. The papers cover ball lightning, radar detection, balloons, satellites, mirages, plasma and similar subjects. One paper compares magnetic field experiments on human volunteers with close encounter reports. It concludes that effects from such fields are 'uncannily similar' to what witnesses describe.

# UNCLASSIFIED UK RESTRICTED ## 'ANGEL HAIR' 1. It is believed that this fibrous material resembling filaments, spider webs or candy-floss-like streamers is formed by reciprocal attraction between polarised dust particles. Sometimes the material is sticky. It can be carried large distances before being deposited and has been likened to long chaff and has even been named 'spacegrass'. It can leave a smoky or misty deposit. The thin filaments appear to be an electrostatic precipitation of atmospheric dust, which is unstable, and which eventually disintegrates and vanishes. On at least one occasion a UK witness has collected what was probably 'angel hair' in a jar, believing it to have come from a 'UFO' which "hovered at the bottom of his garden". The author of this report personally observed this material drifting in a light breeze in Norfolk on a hot but breezy summer's day in 1997. ## METALLIC ARTEFACTS 2. Although no such artefacts have been found in the UKADR, it is claimed in Russia and Ukraine that items have been scientifically analysed. The results are not known. The Russians, like the USA, have never produced the artefacts which are claimed by some media reports to have been found. This seems to be quite extraordinary in view of the fact that it would be reasonable to expect that this might solve the extra-terrestrial hypothesis of 'UFO' origins once and for all. The Brazilian claim of 'extra-pure aluminium' artefacts was not sustainable after analysis. ## SUMMARY 3. No proven tangible artefacts have been obtained by the public for display, or shown by governments to exist. The metallic materials analysed scientifically have not been shown to be of unknown elements. It is a fact that that some materials have entered the earth's atmosphere as a result of meteor activity and have survived to impact. Analysis has shown nothing to connect these with any type of flying vehicle or threat. MOD does not hold any such material
