Blanket bans are a complete illusion of security, after all they legally exist at the moment but it's clear they don't work. The real culprits will take no notice of any pathetic laws like this, only draconian, totally over the top retribution will have any effect. The most effective measure might be to educate the general public that people who fly drones close to airports are the same people who will kill your mother, brother, father etc. when they get it wrong. Let peer pressure do its job, like with drink driving. It is now acceptable to call Plod to have a look at someone who appears under the influence. Education, carrot and stick in the correct proportions.
