After posting earlier about the helicopter’s departure and signal drop, I’ve now noticed it comes back online over Jamestown at 18:34:30 UTC (around 4:04 am local time).
So, in total:
- Departed Adelaide ~11:31 pm local
- Signal lost near Jamestown ~12:19 am
- Back online over the same area ~4:04 am
Looks like it was operating through the night, possibly below ADS-B range for several hours.
