The aircraft is missing and has not been found.
No one knows what occurred or whether the pilot and passengers survived.
To all those with fabulous crystal balls, please refrain from idle, ludicrous, wild speculation until the full and true facts are known.
None of the above will change the ultimate outcome. However, if discussion of the possible senario(s) that have resulted in the current circumstance makes one pilot rethink their risk assessment, then some good will have come out of this tragedy.
