The documentary was made in association with NCAP at RCAHMS in Edinburgh, with research by Allan Williams assisted by Sam Martin. It was originally intended to go out in November but was brought forward at short notice scuppering our plan to have lots of material online to coincide. Sam has worked like a Trojan over the summer and now may of the most important Crossbow sorties have been digitised and are searchable on the NCAP website, with more being added regularly. Pathfinder packs of sites are also included.
