The jets are almost all "visitors" to the field and operate under the auspices of their own SIG.
What has surprised me most is that with the exception of just two within their ranks, they've failed to openly support the SWMAC -- despite the fact that for six years we've made our facilities available to them, mowed a huge grass area (which is actually at the other end of the field from where we fly), provided them with hangarage for their models and I personally have given them all sorts of "spares" (at no charge), machined up new undercarriage components or fixed broken ones and generally bent over backwards to support their activities.
The club has regularly forgone its own flying activities for entire weekends to allow the jets to fly without having to dodge slower models and yet (with only a very few exceptions) yet, they have not paid a bean to our club for all their efforts and the use of the facilities and few of them have even said "thanks" before they pack up, go home and leave us to tidy up their mess.
Now, instead of getting open support for our situation, they're making specious statements such as "do you seriously think that a 400 gram foamie couldn't take someone's eye out?" -- which is a comment made by a guy whose own 150mph F16 turbine exploded into pieces right over the top of the dirt-bike track while there was a race on -- showering those below with model parts.
It seems that you never find out who your real friends are until you need their help I guess.
