Piper PA-31 Navajo VH-TSO looks to be doing a Google like photo mapping operation this afternoon. Starting south at Port Hacking, the aircraft has gradually
moved northwards, tracking east-west in passes 17nm long, and one nautical mile apart (from the western suburbs to just off the coast). The operation has
been performed at 15,500ft and 167kts, and departed Bankstown Runway 11L.
