Came across this video of aircraft landing at LHR
,
If you look closely, you can see an object tracking in front of the landing aircraft and then something falling down.
From second 1 to 10 you can see a black dot slightly left (viewers point of view) and above slowly coming closer and then you see an object falling down.
Seems to be a drone strike according to me rather than a bird strike, but I can not find any reports of such an event.
What are your thoughts?
