    Just from a quick Google search, the Griff 350 can carry a payload of 200KG, so it's not out of the question that some very high end drones weigh that much themselves with all the equipment they have on them.

    The largest drones I can find (admittedly from a quick Google) can carry up to 20Kg, and operate for a maximum of 20 minutes.

    The Griff 350 on here: http://griffaviation.com/the-griff-fleet/

    Can carry 200KG, with a battery that charges in 1 hour.

    A few battery packs and you can cause a lot of havoc.

    Wow that 350 IS a monster. However at 280cm by 265cm by 80 cm it is not the sort of kit the average amateur could afford or fly covertly into airspace. I would think also that the thing would be very easy to spot and certainly show up on radar. Moreover, it would be easy to trace as only specialist companies e.g film studios, SAR teams , etc. would buy them and they are not exactly mass production kit you can simply go into a hobby store and buy. I also doubt that there would be any likelihood of them being flown maliciously or accidentally into airspace.
    I am surprised something of that size and load capacity does not qualify as an airframe requiring some sort of licensing and airworthiness certificate given the damage it could cause to property and risk to life if it came down.

    Most pro drones have blocks to prevent them being used in restricted areas, including around airports.

    Correct. I must have had US ton selected which is 142lb and neglected to divide by 4.

    1 UK ton is 160 stone, 1/4 being 40 stone.

    Even as a drone owner, I believe that all drones over about 30cm across should be licenced (or the 'pilot' should), registered and insured.

    16 oz = 1lb.—- 14lb = 1st.—- 20st =1cwt. —-8cwt = 1t. Easy. Why oh why were metric measurements brought in. o_O
