And the spark
Anyone who would like their drone in a last ditch scenario to not actually crash
Right, so every takeoff you go to an area with a 5m radius.  You completely sweep the area removing even the 2 inch small stones on the floor.  You then go out pulling all the long grass, weeds and plants over 1/2 an inch tall.  After that you make sure that 5m radius is completely flat, there are no trees anywhere near, no other debris and no wires.
Then you fly.
Do you not see that as somewhat restrictive in terms of site choice and launch location for a "go anywhere" drone?
Because if you DONT do the above and your RC goes down or the somewhere locks the drone will come back and can EASILY damage itself on these obstacles.  You may not have the choice of whether to auto land or manually land.
Firstly, the study was widely criticised as being unreliable statistically.
Secondly, there's a reason the most accurate, foul weather precision approaches on commercial aircraft can ONLY be flown on full autopilot.  Because they are more accurate and make far fewer mistakes than a human.
