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 ## ODOURS 1. Some cases have occurred where peculiar odours have been reported. These seem to be produced by microwaves or high energy electrical fields. 2. These effects are well understood and can be replicated in the laboratory. Normally the smell is described as 'sulphurous' 'electrical burning' or ozone-like. 3. During electrical discharges in the atmosphere many electrical compounds are formed. Nitric oxide, for example, reacts with other atmospheric gases to form nitro-benzene which smells like bitter almonds. 4. The slow decay of activated nitrogen can exhibit a white glow and may be the reason for white trails (or 'tails') sometimes described by witnesses, whether or not the witness has smelled the chemical reaction. 5. Reports have been received where a 'strange odour' hangs in the air for some time after an event.
