I don’t see our bird flying until ’08 as we still have some issues to deal with such as what will we fly it on. The loki dart also requires a special helical launcher that spins the bird up to…   Read more»

Just curious about you comment about the mass of a large booster affecting the seperation. Wouldn’t it be more of a question of drag? Isn’t point of separation is when the force of drag on the booster is greater than…   Read more»

After watching Apollo 11 at age 3 I knew I wanted nothing more than to fly in space. But back then, test pilots couldn’t wear glasses so I was SOL. Found model rocketry through the Cub Scouts (1st Rocket: Estes…   Read more»

I remember taking an old double-barreled cork shotgun (corks were attached to the barrels with string, you just shot the corks out of the barrel, and the string kept them handy). Well… I took the corks off and made darts…   Read more»

one thing that I have noticed is that I have a love of darts, golf, rockets, and markmanship shooting. These are about projecting your will over distance. Anyone else that way?JS

Yet another older guy… 53, started making my own rockets back in ’63, two years after I got my Chemcraft chemistry set at age 8… until I found, like Warren and Ed, an ad in Boys Life about Estes or…   Read more»
