Contrary to the initial reports, no-one on the ground died as a result of the accident. Some were injured, a few seriously.
For the moment, and we all hope it remains this way, the only fatality was the engineer.
There are anomalies in the initial preliminary report so perhaps until all the evidence has been collected and a final report delivered, some contributors here may choose to moderate their willingness to attribute blame and concentrate on the well-being of those unfortunate enough to have been involved.......especially in this particular thread.
