For those looking for more photo's from the Follands archives, I'm afraid the short term answer looks bleak; however I hope to get more, and some insight into flying the Gnat, soon.
I must say from a distinctly academic point of view I'd love to know more, for instance the seat - the archives showed several firings of a fully kitted out dummy, then what looked like a real human test, ending with a group outside a pub, which seems very understandable !
