Don't disagree it's arse covering but I guess if I was in that position I'd want my arse covered! Ref the Flying Schools, I don't think the intention of these NOTAMs is to stop people flying (hence Advisorary not Mandatory Avoids) but to inform and arse cover! And some of the NOTAMs (Fast Jet Areas) have to be requested/published as above FL245 certain Upper Routes are rerouted as per the JOINT WARRIOR AIP Supp. Doesn't help that there are a number of military exercises all happening at the same time but I guess that is military planning for you!
