The first minute of this is real (we haven't looked at the rest, yet). It shows a craft crashing in South Africa, with subsequent debris. This is the fourth such shootdown we've seen, three of them with our own eyes.
UPDATE: The wreckage/debris shot is fake, but the shot of the ship crash/huge explosion is genuine. The craft itself was totally burned up, there was no wreckage as seen in the video. Maybe a few burnt pieces of metal, but they'd be very very small.
