A certain military aerobatic team flew into NWI prior to displaying over the east coast this morning. Into circuit in big break and all frames broke to the right as they flew down to the 09 end. I thought "Well that is not normal into here". Suspected that the team were avoiding split breaking over Old Catton. Post display, a nice flypast in Big Vixen.. then the normal Big Vixen in to circuit break in both directions with smoke.. Good to see.
