This is a good up to date book (2014) about the research of Rendlesham case. It contains mainly the views of Penniston and Burrough. With Chapters where Pope writes about the circumstances and other things regarding research. The book gives not only an update on the status of research of the last years; it can also be a good entry point who havent read previous literatur about Rendlesham like that from Georgina Bruni. However it's not fully complete since the views/opinions of Charles Halt and Larry Warren are not that prominent in this book.
