Re: I hope you drone pilots have decent insurance
"Read the report. Its all in there. Along with the fact that the helicopter company had found the reporting advisory scheme unworkable so had abandoned it - so the military had no knowledge of the helicopters presence. So whose blame was it?"
The report stated that the (widely) "abandoned" scheme was unfit for purpose and one specific to pipeline inspection was created (PINS) as a result of the accident.
Try turning the problem around and looking at it from the Helicopter crew's point of view. There was nothing more they could do to tell the Tornado crew what they were doing (they kept ATC informed), and there was nothing that the Tornado crew did (or could) do to warn the Helicopter crew they were in the area (in real-time).
I am not saying the Tornado crew did anything wrong, but the accident does illustrate that an aircrew that is not engaged with ATC and not paying enough attention to what's going on outside the cockpit is just as much a problem as a numpty drone operator. I did witness a number of near misses between Fast Jets on low-level exercises - it was a known problem long before Farleton.
