Not knowing the full details, so I'm NOT taking sides. However, as has been discussed on other threads, eg when Hairyplane reported infringements of a display at Old Warden, unless you select exactly the right brief on the AIS notam website, perhaps on a narrow route briefing, then not all notams were being shown. Unfortunately there is no decent help on their website to ensure you get all the correct information/ do the correct selection.
I tried several times searching for info regarding an air display at Old Warden, and the AIS website was NOT showing one display, but showing another closure that wasn't a display.
So maybe......? AGAIN I STRESS NO SIDES BEING TAKEN
