I think we have to be careful, as ever about prejudging accidents like this.
Condemming light twins out of hand on the basis of this accident is a little unfair.
As usual if an aircraft is operated within it's limits by a current pilot, then you minimise the risks.
I read a news report today, quoting another pilot who overheard the pilot arguing with the passengers about the amount of camera equipment they were loading. Eventually apparently he gave in. I suspect the argument applied against him was that the aircraft that brought them in had no trouble carrying the load.
There was also a comment that he had trouble starting one of the engines. As anyone who has flown pistons (ie all of us, nearly)knows. Sometimes they don't like starting, it has no bearing on how they run. There is talk of an engine failure, but no one knows yet. It's all too soon.
People are jumping to conclusions.
