I don't have any experimental data, but my mental models pull up: 1) chucking a chicken bone into an insinkerator vs a penny. 2) a hunk of wood vs a hunk of w

  Good examples, although I wonder if the relatively low speed makes a difference. The closest comparable that I can find is this: http://www.discovery.com/tv-shows/mythbusters/videos/chicken-gun-minimyth/ http://www.discovery.com/tv-shows/mythbusters/videos/chicken... They shoot a frozen versus thawed chicken out of an air cannon, and conclude that the impact force is identical for both. I'm pretty sure that adding some metal bits inside both chickens wouldn't make much difference. Density would make a big difference though. A basketball and a 1.75" lead ball have about the same mass, but the lead ball is going to do much more damage. But not because it's harder, but because it's dense and cohesive. I'd guess that a drone of comparable weight to a goose is going to have a greater impact area, even though some of the internal bits are much harder, and I'd guess this is going to be more important for the level of damage. Here's an article that supports that view that mass is the main factor: http://spectrum.ieee.org/automaton/robotics/drones/what-might-happen-if-airliner-hit-small-drone http://spectrum.ieee.org/automaton/robotics/drones/what-migh...
