In this recent study conducted by researchers at the university of Dayton, a Phantom II drone (popular hobbyist drone) was launched into the wing of a GA aircraft at 238 mph. The results were shocking.
The drone punctured the leading edge of the wing and continued until the entire drone was inside the wing. See the screenshot below:
In my opinion, drones are even more dangerous to aircraft than birds because they have sharper, moving parts that can puncture the wing. The drone in this test was only launched to 238 mph, while a commercial aircraft would impact the drone at a much higher speed than that.
