What happened
Delta flight 394 from Maui to Seattle diverted to Honolulu after an unusual cabin odor was detected shortly after takeoff. Four passengers received hospital treatment, a crew member sought medical care, and fuel leakage was found after landing. The aircraft was temporarily removed from service for investigation.
Why it matters: The incident highlights operational and safety risks from unresolved cabin-air contamination and related technical faults on long overwater flights.
