UK Missing Person Behaviour Report 2011
Everyone that knows me well, knows how much importance I place on good evidence for everything we do. To get this evidence takes time, effort, hard work and research! I’m so very pleased then that Dave Perkins, Pete Roberts, and Ged Feeney have published their latest report into the UK’s misper stats. The report can [...]

Combined Visual and Infra-Red Search
I came across the following on the New Scientist website today. Could seeing with heat and light simultaneously improve search and rescue missions? Nathan Rasmussen of Brigham Young University in Provo, Utah, thinks so. He has created a hybrid video system that integrates visible and infrared footage into a single shot. [Read more here...] It definitely [...]

Elements of the Optimal Search Problem
Lawrence Stone defined the elements of the optimal search problem in his 1986 book, Theory of Optimal Search. This was paraphrased extremely well by Cooper, Frost and Robe in their 2003 report – Compatibility of Land SAR Procedures with Search Theory as quoted below; A probability density distribution on search object location and state (so [...]

Missing Person Behaviour and SAR Callout Study
After several years of messing around I have finally decided – with much prompting and encouragement from others – to get around to studying missing person behaviour within the lowland search environment. ALSAR and LSDog teams deal with only a tiny fraction of all missing persons and indeed deal with only a small fraction of [...]

The Use of Mountain Bikes for Search and Rescue
On Friday I posted a news item on the First National Search and Rescue Mountain Bike Instructor Scheme being run by Black Badge. This sparked a debate; on whether it actually was the first but also on the use of mountain bikes for lowland search and rescue. A number of ALSAR Units now run mountain bike [...]
