Would it really be so expensive to just say, "hey, we'll retrofit two angle sensors and updated warning software to every plane that doesn't have it, and it's standard going forward"? Did they really save any money making the 2nd sensor and the warning signal optional?

I spent many hours clicking away in galaxy zoo, less in recent years. I must say I miss the rich, multi-topic BBS style forum of the old galaxy zoo. The newer projects have "discuss this image" buttons but they don't encourage browsing or interaction or sharing with other users because they only lead to "this image" discussion. Any chance of something like the old forums returning?
