VDR would have saved months

摘要

Without any VDR data to go on, the investigation into the March 2006 grounding and sinking of BC Ferries' Queen of the North was "prolonged ... by several months", Canada's Transportation Safety Board (TSB) said in its investigation report, published at the end of January.In fact, the report is peppered with references to VDRs and the benefits they could have brought, and the investigators' frustration is hardly concealed. Faced with little objective data and contradictory witness statements, the investigation had to use "investigation techniques that would have been unnecessary had a VDR/S-VDR been installed and recovered", according to the report.
