Most research groups tend to be made up of small numbers with a core of two or three people and we are no different. We both started visiting crash site with family members during the 1990s and started visiting crash sites and researching their histories together in 2001. Since then we have co-operated closely with other researchers in the region and have still on occasions visited sites with family and friends.

The name Peak District Air Accident Research came about from us being invited to install a display at the RAF Millom Aviation & Military Museum in 2004, at this point it was better to have a name to attach to everything and to show people what we do, research aircraft accidents in the Peak District, however since then that museum has closed down.

We are:

Alan Clark, from Romiley near Stockport and started visiting crash sites in February 1999 and since then have visited over 500 crash sites.

Mark Sheldon, from Poynton in Cheshire, started visiting crash sites in April 1992 and has since then visited over 600 crash sites throughout the British Isles.

This photo was taken at the crash site of Bristol Blenheim Mk.I L1252 in the North Pennines during early 2008.

During 2008 Alan & Mark joining Nick Wotherspoon of the Lancashire Aircraft Investigation Team to write Aircraft Wrecks: The Walker’s Guide, a detailed volume recording high ground aircraft crash sites in the British Isles which has been printed in both hard and paper back. While it is now a few years since this was published it is still available, and may well be updated as the number of sites we located and record increases.
