And the counter prosecution case might be that he could have used the freephone number which has been available for years ??
There are two available.
One which is a recorded message giving airspace upgrade information and temporary Restricted Area information.
0500 354802
And one which will put you through to a human where you can get a more specific brief on the same.
0800 515544
Either would have made this pilot aware of the display and the airspace affected.
Both are detailed in GA Safety Sense leaflet 18A Military Low Flying published in 2000 (the previous version was no doubt published a lot earlier).
GA Safety Sense Leaflet 18A
The pilot admitted that he had learned his lesson and, by inference, that his airmanship was not what it might have been.
Let's not try and blame the system but for once let the pilot take responsibility for his actions. He will be a better pilot for the experience and all are fortunate that the incident did not have far reaching consequences for himself, the Red Arrows, and the public.
