Parabellum. Purple airspace is a temporary restriction (IIRC 15 minutes before and 30 minutes after published timings- unless it has changed) - are you saying that on the day and in the area in question there was a Royal Flight in the vicinity - in which case perhaps both parties were in the wrong. Or are you suggesting that Purple Airspace is a permanent fixture - which I do not believe to be the case.
Canadian Break - Sorry, my point was that because due weather and availability of aircraft for jumping there is a constant backlog of people who are either initial or recurrent parachutists, consequently I believe that task should have a high priority when the aircraft is available and the weather is good. I mentioned Purple Airspace to give an indication of how high that priority should be without including the parameters of Purple Airspace, only it's priority.
