This article [1] notes that "The incident, ...came the same day 25 people were injured, six seriously, aboard a Hawaiian Airlines flight from Phoenix to Honolulu during severe turbulence in the vicinity of Maui."

A local source [2] comments on the weather that day: "On the day this happened, we recall well that the Hawaiian Islands were in the midst of an exceptionally strong wind and rainstorm that was, even for Hawaii, highly unusual."

Correlation, not causation, but a speculative explanation nonetheless?
