Allow me to introduce myself…I started HPM (Henry Paul Matthews) Publications in late 1994 with the objective of preserving in book form the detailed history of experimental aircraft (or X-planes) and test pilots. So far I have published more than 25 books. All but one are the FIRST and so far ONLY books about their respective subjects.
These books fill a gap in the aviation history library and will remain useful historical reference works for generations to come.
I have come a long way since publishing X-Planes Book-1: The Secret Story of the Soviet Space Shuttle. A lot remains to be done and I realize that I am too late to save many X-plane histories, but I do my best. It is a service to future generations, and I hope that you will be with me. To the many enlightened individuals who believe in me and who helped and still help with their time and archives, I say a very big thank you.
