So let me get this right, a MQ-9 has a cruising speed of about 190 mph, That SU-27 was approaching this lead sled of a drone with no flaps down or speed break extended, yet it passed over the drone dumping fuel with not even a high nose angle to keep it from just falling out of the sky at that slow speed? For the SU-27 to come close to the drone without just flying past it at high speed it would need full flaps and speed break with a nose up angle because the SU-27 at 190 mph is on the razors edge of departing flight. I'm calling total BS with this video.

SU-27 stall speed is around 125mph. The SU-27 is coming from the rear, so its probably going maybe around 350mph (assuming MQ-9 is going 200mph).
The video may be BS, but I don't think this reason is conclusive.
