> I disagree with your assessment. I myself am certainly not a lawyer, but the way I interpret that language is for something to be considered an act of terrorism it has to meet a criteria from section [1] AND section [2]. I agree that the planned drone demonstration meets 1c, but I don't think it meets any of the criteria from section 2.

Also not a lawyer, but it seems pretty clear to me that flying drones around an airport can be considered to fall under 2(d): "creates a serious risk to the health or safety of the public or a section of the public".

The fact that the airport can respond by closing down operations to mitigate the risk does not make it OK, any more than phoning in a warning before setting off a bomb makes that OK.
