I haven't read all of the posts in this thread so I don't know if this was posted or not but there have been at least two reported UAV vs. full scale midair collisions this year. One in Illinois and one in California to go with the long list of near misses. Although unconfirmed, the Illinois collision generated damage that could not have been from a bird strike.

Here is an old one under "controlled" conditions of the military.

It won't be long before someone gets killed in a midair collision with a UAV.
