Re: Pink Unicorn?
Thanks to some actual tests on aircraft components we know that the amount of damage a quadcopter can cause is quite limited, its certainly no worse than hitting a bird.
Its difficult to regulate stupidity but fortunately modern quadcopters are equipped with multiple cameras that are used for collision avoidance. (Look up the latest DJI product -- its tiny, under the FAA weight limit for registration, and is verging on the intelligent.) We can only hope that helicopters will gradually get similarly sophisticated avionics as these inexpensive consumer products.
