Cap 56 and all those other conspiracy theorists, the reason why nothing further has been heard of the incident is that there is an active investigation going on at the moment. The safety dept and all other related bodies are flat out trying to get to the bottom of this, hence after the initial report, all is quiet.
I suggest we all do the same and wait for the final report. Wether it is released to the public is a different matter but the way we have been irresponsible with all the other "confidential" reports I would not be suprised if they decide to withold it.
