Everybody knows what a cold feels like: miserable. The first cold virus was detected in a milk tooth shed over 30,000 years ago and ever since, the common cold has been a bane.

Yet while sore throats and blocked noses are annoyingly familiar, the processes that lead to them are not widely known and often misunderstood. Processes like the misdirected immune response that makes us ill with a cold instead of protecting us from illness. Like the way heating a building enhances cold virus transmission. Like the way that most cold viruses can only exist at all thanks to the society we’ve built over the last few millennia.

And, most importantly, what we can do about them.

The Rendlesham Forest UFO incident of Christmas 1980 ranks as one of the top ten UFO cases in the world as voted by UFO believers, and is often described as the ‘British Roswell’. Evidence for a series of sightings spread over two nights includes eye-witness statements from security guards at the US Air Force base near Woodbridge in Suffolk, a memo from a high-ranking USAF officer to the UK’s Ministry of Defence, and a real-time tape recording of events as they unfolded. This talk looks at the main points of the case and explains how the witnesses were fooled by a series of natural and man-made objects. The Rendlesham case is an instructive demonstration that UFO sightings can never be taken at face value no matter how reliable the witnesses may seem.
