Theory Briefing
- Royer's team had placed hydrophones at six southern Indian Ocean sites just weeks before MH370 disappeared on March 8 — an accidental front-row seat to the mystery.
- The acoustic recordings may contain a signal tied to the plane's final moments, potentially shifting where searchers should look.
- Underwater sound can travel thousands of miles with surprising clarity, meaning a crash impact could leave a detectable acoustic fingerprint far from the wreck site.
- The new clue reopens the question of whether previous search zones were drawn from incomplete data.
