Airbags, parachutes, Rogallo wings and all that

On Pressure Fed Rockets and Scaling

Well, scaling seems to be my pet issue. I recently wrote something not entirely well reasoned in a comment at Paul Breed’s. (For some reason Chrome complains about blogrolling.com malware there so continue if you’re sure you’re safe.) So let’s … Continue reading
