And just to highlight my point. Going through your list of infringement occurences:
AVIONS ROBIN DR400/UNKNOWN/Cruise/ORTAC/18-05-2013/201305603
Infringement of the Channel Islands CTR (Class A) by an a/c squawking 1177 at 3000ft.
A/c identified via London Info as a Robin DR400. Standard separation maintained.
The Robin DR400 called 5nm inside the Channel Island Control Zone, was indentified and vectored West to remain clear of Alderney airspace.
This is suspiciously due to ATC co-ordination failure because the aircraft should have been handed off and suitable clearance arranged long before entering someone else's sector!
