I seem to remember that CanonJohns40D started this topic off because some people who are not interested in mil ac were getting sniffy about them being reported on the 'Interesting Aircraft' topic.
I'm sure lots of our members have found it useful and as far as I'm concerned anyone should be able to post about any mil ac that they find interesting. Remember, some people live in areas that are rarely visited by mil ac and so find it exciting when one comes up on their box and wish to share the experience.
If you want to start a topic about 'military gems' then go ahead and do so, but don't complain if you find other members' idea of a military gem does not accord with yours.
As for prewarning of mil ac coming your way. ANRB is not much cop for that, for many reasons. For that you need PlanePlotter, preferably with multilateration.
