I agree whole heartedly that the Online wars are very enjoyable, my group Air Group 51 participates in Ground Zero SEOW campaigns

We are getting ready to start a new campaign soon, we use the HSFX 5.1 install for our basis. AG-51 also has a Jet Pack 1.1 install for HSFX so we can do the Korean conflict coming soon. We get together as a squad and fly against the 69th GIAP (we get a stray AVG pilot once in awhile too) on Tues, Thurs, Sat nights at 2100 EST and 2000EST on Saturdays.
