I am saddend to hear that the "run and break" is still being performed at civil airfields without all the traffic being briefed for what is about to happen.
About three years back a Yak and a Cessna hit each other , the cessna was flying "downwind" and the Yak was performing a "run and break" , this resulted in the death of three people.
The "run and break" is a military operational requirment as set out in posts above , I,m sure that the military would not think of performing a run and break without all pilots being fully briefed and yet you tell us that at a civil airfield this is being done with some traffic who are unsure of what is going on.
This can only be another accident waiting to happen.
