It looks like REX178 VH-ZLO had some problems over the Blue Mountains this afternoon, and returned to Sydney
after a couple of orbits just west of Richmond. I only heard the back end of the ATC transmissions, so not sure
what happened.
Just checked the weather, maybe that was the problem ?
Gulfstream G-V HB-JKI made a large diversion to the north after departure to work around the weather. ATC said the
front was moving at 30kts and was 15nm wide and 100nm long.
