Regarding flying rockets or using usenet? One has little to do with the other.
You didn't mention your denomination. While I find it commendable to monitor and investigate a potential activity of your students, the manner you have gone about it is slightly suspect. No one here knows if you're Jim Jones or Billy Graham. Anyone can say they are a Reverend.
I know many true Christian rocketeers, from a number of churches / denominations. Most recently, last Saturday our local club had a Royal Rangers group come out to fly and they had a great time as did the other club members there flying with them.
Please correct me if I'm wrong but if I'm reading your post correctly, you have generally decided rocketry is not a good thing and may possibly corrupt your students. That's fine but if all you have to go by is what you've read on rmr, you have a very finite sampling to use as your guide and come across as being judgemental. As a pastor you should know the difference between discernment and judgement. Do you hold the same opinion concerning all sports activities and secular occupations? After all, there are many negative role models in sports.
I'll accept you at your word but from one Christian to another, you might want to remove that mote.
