Wow - smoke detectors and Tang AGAIN you assume that none of this stuff would have been developed without the space program. Just not true. If there is a consumer demand for it, then it will get developed. Government funding is the least effective way to get stuff done. Just look at the difference between the post office and UPS.
See, it is true. I just proved it to you and made you look like an azzhat in front of all your lib troll friends.
