The Dutch Safety Board has decided to consider if this question can be answered. The Dutch Safety Board does not make statements that are based on uncertain premises or assumptions. Depending on the findings made, the Board will make a judgement as to whether the investigation has produced sufficient (factual) information to report on this matter.
