What is a bit frightening with this info is:
1) how cheap and crude you can today make an effective ground to air weapon delivering an explosive charge..
2) This time it was against a parked aircraft with impact velocity in the 60 Kts range I am guessing . Now imagine the same impact and subsequent explosion with an aircraft doing 2 or 300 Kts
The only good news is that to catch a 300Kts moving object with a 60 Kts drone you can only do this opposite to each other , and will need very serious skills by the drone pilot that I doubts those idiots have.,
