Good that he was caught. Spread the word to other droners.
He is going to have to pay for the damage. Probably 10s of thousands of $
that all well and good, but actually how much damage can a drone do to a helicopter? Unless it was one of those big ones made to carry a 20lb camera... heck I have gopro karmas and DJi Mavic Pros and theyre nothing really! I could break them apart with my bare hands if I wanted to...
