Rotorspeed, you have it nailed - this ridiculous service is a sop to the coroners court to show something is being done. Will it prevent another tragic accident like Heather Bell's? No of course not (wearing a riding helmet might though) - it is worse than closing the stable door after the horse has bolted, at least that prevents another horse getting out.
Instead of being robust about the cause of the accident the politicians forced the military to roll over and bring more unneccesary crap into the mil aviators life.
As for the service - let's hope it's better than what we get from the Booking Cell "Mixed traffic, no late warnings".
Feat of Ar*e.
