While back Muppets had guys on different countries (knits/rooks) and organized a mission on both countries to do a fighter sweep into each other using classic plane lineups, it was a total blast screwing around at 25k.
We should try to organize this again, it was quite fun.
It was I that set those up! I was trying to break up the monotiny of a typical MA evening, AAjager was gracious enough to be enlisted as my opposing mission generator. Jager and I had to postpone the launch several times before we had somewhat equal #s. Other muppets were kind enough to join my mission, then more and more peeps found it credible I guess and joined. I think the 1st fight was about 50ish vs 40ish at the merge. The second saw less #s cause a few folks got butt hurt in the 1st match up. It is difficult, like herding cats. If I remember correctly it was spit 5/ Hurry mk2 vs 109F/190A5. Simple rules were No merge HO, and coalt 5K. Most everyone thought it was very fun, we tried a couple days later and got almost no takers

Weird bunch the AHers are

If you set it up, you must be patient and let them come, a few "known names" on each side will attract those who are unsure. Choose a counter part to generate an opposing mission against you!
It was fun!!
Good luck
