The speed of the jet at 500 mph would likely be blurry in the photo of real although I supposedly depend on your shitter speed.
It's fake, but even if a jet of this size impacted a mavic, I think there would likely be little to no danger to the passengers or crew. The mass of a mavic is significantly less than that of a Canadian goose, and these planes are tested against bird strikes.
Not suggesting that uas try to share airspace with manned aircraft, but if the worse case scenario were to take place, the risk to giant planes is likely very minimal.
