TechSpot: A British drone enthusiast known only by his YouTube user name, gasturbine101, has built a home-made flying (well, hovering) machine using 54 counter-rotational propellers.
A $230 pocket-sized drone that can only fly for three minutes.
In the span of 13 months, eight drones have crashed.
Attacks like this one are likely to become more of a problem in the future.
