Level-2 Certified After All?
I got my new Tripoli Rocketry member card in the mail yesterday, and lo and behold, it says "cert level 2." I tried for level 2 three times last summer, and *supposedly* failed each time. Evidently one of those flights (probably the last one) was not such a failure after all.

Rocket Science 101
I'm going to start a video series on YouTube on basic rocket science. Nothing too complex or too basic; I will be starting with concepts like Newton's laws and gradually get more complicated to describe the motion of a rocket. At the end, I will give an introduction to the actual engineering of a rocket (model rocket).
My aim is to get more people interested in the field of aerospace engineering, specifically rocketry and spacecraft. Even if only a handful of people watches these videos and only one of them is inspired to dig deeper, these videos will have been a success.
I will post a short "syllabus" soon.
