Curtin University Acoustic Signals
Acoustic signal received at Rottnest at 1:30am UTC. The final ping arc is about 2,000km from Perth. Sound travels 1500m/s in seawater. This means it would have taken 22mins to reach Rottnest from the final ping arc, which would be 1:08am UTC. Final satcom communication at 00:19am, 49mins difference. Is it possible to glide 49mins in a 777?
