Rockoons, aerospikes, and a MiG29

Issue 4. Firstly, I want to apologize to those of you who signed up on the website and never received the newsletter. In all honesty, I added that feature to the website when I first launched it and then promptly forgot about it. The lists have, however, now been combined, and you can expect a mail from me weekly. There are 180 of you this week, and I want to thank each and every one of you, it means the world to me!
