In the past the RAF had no interest is the VGS
No doubt, but the MOD as UK Military Air Regulator was mandated to take a very close interest in the airworthiness of VGS aircraft. That it failed to do so is clear, why it failed to do so is the scandal that now must be exposed. Aviation doesn't do politics, it kills given half a chance. When you are dealing with other mothers' kids that's a clear no go.
As with any air accident, there are often many holes in many slices of the Swiss Cheese to line up. The UK Military Airworthiness slice is now more hole than it is cheese!
If this was only about the ACO glider "pause", it could be turned around in a thrice. Unfortunately it is about far more than that, though the MOD would much prefer those affected to think along parochial lines. That's how they dealt with all the other fleets affected by lack of airworthiness (usually at the cost of fatal air accidents). They even have a term for it, "stove piping"!
