Interesting bit of blame-shifting - the rumour is that it happened at Boscombe, not Aberporth, when the crew said it was too foggy to fly but were ordered to get it airborne by a senior operator (with no UAV flying experience). The Master Override was used to try and land it and it crashed.
It is possible this was another accident entirely but the similarities are rather worrying.
If you read the convening authority's comments at the end of the SI, you will see that he refers to the BD accident and that an SI will be published later this year. He remarks that there will likely be many similarities in the causal factors.
