Down under, we had a situation a while ago where a tanker did some flying near Sydney with fighters in company (photo opportunity). Caused quite a panic, because uneducated Joe Bloggs thought the fighters were trying to shoot the aircraft down.
So when the first AEW&C Bird did a similar thing early this year (B737 with a Hawk as the photo bird) the RAAF put out a press release explaining what was happening, and included times/tracks etc so as to not alarm anyone.
