A lot of people are arguing if the drone is real or not, was it shot down or just landed due to a malfunction, or this is replica or not,
Probably some time will pass till we will know for sure what happened, but this incident reminded me of an event in WW2.
A US Army bomber took of from Benghazi in Libya in 1942 and had to return to base due to navigational problems but got lost on the way back so the crew bailed out. In 1958 a British Oil Explorer group found the airplane, landed on its belly and almost fully intact. So the plane just drifted for a while after its crew jumped and then made a soft landing at desert ( or crash since no one was inside the aircraft)
The name of the airplane is Lady Be Good, it is still in Tobruk, Libya at an Air base there,
I shared this story with you because, there are some analysts who say it is very difficult for an aircraft to survive a crash from high altitude, but in my humble opinion, a drone just drifting to a flat land could survive intact.
Also, that drone looks like a prop or home-made but I havent seen the real thing so I can't speculate on that,
