Do you doubt that the sUAS did considerable damage to the leading edge of the wing and "potential" damage inside the wing? I believe they proved pretty much exactly what they intended to. It proves that even a small Phantom sized sUAS can do damage to a General Aviation aircraft.
Here let's "again" question the "rebuttal" that DJI's attorney tried to push out to the people looking for a reason to NOT believe that this is a very real possibility:
An Aeronautical Lesson for DJI’s lawyer, Brendan Schulman
Oh come on... it did roughly $250,000 damage (both rotors had to be replaced) and keep in mind that is a COMBAT aircraft... they happen to be a little more "Robust" than General Aviation aircraft.
Also the sUAS was operating in a RESTRICTED airspace, well beyond VLOS, and the operator had lost contact and the aircraft was in a RTH mode. Which part of this, in any way, makes the sUAS operator not TOTALLY at fault on many levels? Keep in mind that it is our ultimate responsibility to See & Avoid any and ALL manned aircraft.
