Subsequently, the aircraft dove into the water, striking the surface right wing first. Upon impact, the floatplane flipped inverted and sank.
Final Resting Position
The aircraft came to rest submerged and suspended upside down from the floats, which remained on the surface. All five occupants of the floatplane died by drowning while inside the airplane.
