Super scary. Those big drones should not be operated around people, even in a professional sports context.

Are we sure that depleted battery in the cold can be ruled out? Hirscher was the second last skier that mattered. So even if the remaning battery would have become marginal (even more accelerated due to temperature), there could have been quite some psychological pressure on the pilot to stay up there and film the topshots....
"interference on the operating frequency" is the "dog ate my homework" for all drone pilots everywhere. Remember that. :-)
@Bill,
we can spend days, weeks , months on speculations.
Pls read my C&P
WooKong-M Waypopint Precautions
to get answer to your question about failsafe algorithm with DJI.
It looks like the Italian Government has violated drone fly basic safety standards,
having failed to adopt EU regulation on drone fly safety rules in Europe to ban drone fly over the crowd.
My last C&P since necessary and required to clear the facts
from

FIS statement read.
..
"Even if -- unlike in Austria, Switzerland and other countries -- drones are authorized to fly over a crowd during events in Italy, FIS and the host broadcaster will work together with all the involved parties to see what occurred during the crash and ensure that this will not happen again."

@Daruis, I have no idea what you are saying other than cut and pasting text into comments. What's your point?
The question is, why did the operator engage the nuclear option, and why wasn't the normal failsafes engaged, i.e. hover on signal loss, return to home etc...?

Flight Termination System developed in 2011

Flight Termination System - Italy standards
http://forum.dji.com/thread-31971-1-1.html
In Italy to be able to pilot a drone is necessary that the drone is equipped with a safety device " ...
This "device" is needed only if you have a license to operate in cities and in very crowded areas. In Italy, If you fly for fun, you do not need that, provided you fly out of cities and over not crowded areas (the rules define a not crowded area if there are "less than 12 people" - funny).
Bill, the Flight Termination system is a separate system using it's own radio link, possibly on a different frequency even. Supposedly that is why that functioned when radio control was lost.
I think the regulators need to start demanding to know why the failsafes do no not appear to be working on the DJI systems. In my opinion, it's not a failsafe event, but a bug in the navigation controller.
Gary, they do have logs, but the data is very sparse, and it's usually impossible to figure out what happened. For example, from what I've seen, they log what the attitude is. But now how or why it go there. I've tried to analyze them before, but all it showed was that it rolled over. It did not show if the roll was intentional.
@Bill,
@Gary,

Lost C2 Link –C2 Link is available and the pilot is able to actively manage the flight •Lost C2 Link State –C2 Link is unavailable and the pilot is “unable to intervene in the management of the flight” –But the aircraft is performing a flight plan that was pre-programmed by the pilot following TBD ICAO procedures so is safe •Recommend states harmonize the Lost C2 Link procedures for pilots and ATC •Continue flight plan, climb to regain C2 Link, or land at alternate aerodromes? •Lost C2 Link Decision State –C2 Link is unavailable but RPS has not yet declared a Lost C2 Link •Short decision time causes “nuisance” Lost C2 Link declarations •Long decision time could lead to an unsafe condition 15 •Decision times depend on Class of RPA and operating region "
