Is this real?
The scale is all off, it resembles an RC drone.
Look at the clouds behind it for a concept of scale. The clouds are unlikely to be very high altitude, implying the aircraft is very close to the ground, which implies that the aircraft isn't that big.
So the conclusion would be, this is either an RC drone (and it feels like a kite to me), or is a UAV / UCAV being tested.
