To elaborate a bit more on @JudoSurfer
's comment: I've lost GPS and/or Controller links before and the RTH / LIP function as needed. In one situation (I was under a cliff, the drone was above the cliff and went behind the edge -- this is when I learned RF is really line of sight and doesn't bend/refract around hard obstacles) when the Drone/Controller link was lost the drone started it's RTH. When the drone got back in sight and the connection reestablished, I was able to regain control and continue flying. (The RTH didn't actually land). The point: I regained control.
During my beach flyway, several things occurred that appear unique to other flyaways:
1) the drone did a runway (literally and figuratively) where I lost control. In fact, the drone breached 3 built in safeguards (Failed RTH, LIP and exceeded max speed)
2) I did get partial control (I was able to regain yaw/rotation control, but not speed, elevation, or direction), but I didn't get enough control to prevent a collision
The fact that the 3 safeguards were breached suggests that the flight controller got corrupt. The cause of the corruption is still up to debate. GoPro says it's due to "environmental factors" (WiFi interference), but I find that argument extremely week. Safeguards that fail are not "safeguards" -- and that is an issues of the flight system, not environmental factors. Stall warnings in modern jet planes should still work if it's raining or not, right? (Frankly, I think the flight controller had a buffer overflow situation, corrupting the flight control parameters.)
Unfortunately, I can verify any of this specifically without getting a copy of the flight log for myself. (And GoPro won't release that)
GoPro uses "environmental factors" as a scapegoat to release them of all responsibilities of a mishap. What I object to is that all of the examples of "environmental factors" that may contribute to WiFi / GPS interference that they have used in my ticket (WiFi hotspots, peoples cellphones, parking lots) are not mentioned anywhere
in their documentation or web site.
NOTE: GoPro indicates that that the drone/controller operate on 2.4GHz frequency range. They don't elaborate if it's within the "WiFi" range.
The only mention of anything is this vague comment in the Karma Warranty doc (Karma_Warranty-MainSKU_REVC_Web.pdf)

(Sorry, didn't mean to rant so long)
Separate and independent to my situation, I am total agreement to this
