which resulted in a crash and everyone dying in the crash.

A bride was on her way to her wedding to surprise her fiancé and guests who were waiting. The helicopter took off in VFR conditions (with minimal clouds) and flew into and area of low clouds and fog, and eventuallly crashed. Terrible story, and unfortunately a textbook no no.

The crash was caught in film from the inside.
