What would have happened to an airliner wing with its leading edge devices? Not saying that there is no danger, but this reminds me of the test where they fed saccharin to rats at rates that would equate to hundreds of pounds per week to humans. You can design tests to get the results that you want.

I agree with you, especially the last 2 sentences.
However, keep in mind the Mooney M20V has a max cruise speed of 242 kts (278 MPH) and that the DJI Phantom 2 used in the experiment has a max speed of 15 m/s (33.5 MPH). So, theoretically, the 2 could have collided at a differential speed of 311.5 MPH, a whopping 30% over than the actual test.
While the test (and the results) might have been "tweaked" to be more dramatic, the results are indeed valid and worrying.
As the article mentioned, nothing catastrophic has happened... yet. I'm sure it's just a matter of time until it does, and the knee-jerk reaction at that time will catch everybody by surprise.
The careless drone operators are playing with fire.

The risk is real, I've seen drones while on approach, but this was highly exaggerated
Wonder how they managed to get the drone going at 230?

DrRumack wrote:In the experiment a drone was shot directly at the leading edge of the wing. In a real world scenario the airplane (and the wing) would be traveling through the air at a couple of hundred miles an hour. The speed of the drone would probably be inconsequential.
DrRumack wrote:Once the plane approaches the drone, the lightweight drone (2 lbs/0.9 kg) would be displaced along with the air traveling above or below the wing. While there might be some slight contact, the drone would not hit the leading edge of the wing and would not penetrate it.
According to earlier studies by Transport Canada (2004), 15% of birds hit the aircraft nose. The wings and the engines both sustain about 13% of bird hits. The aircraft fuselage gets 11% of the bird strikes and the landing gear about 9%.

This way any unauthorized UAV would be instantly disabled and eliminated. And the idiot who flies it there would learn the hard way to stay away in the future, hopefully...
