Video of MH17 Hit by Missile? (7 main questions)

Reader David sent an email and accompanying video that purportedly shows the Malaysian Flight 17 being hit by missile. Let's take a look.

David Writes ...

It appears as if the right engine and wing area took the hit. The camera operator is able to record the moment of impact in the first 2 seconds of this clip. Note the smoke burst left behind on impact with the #2 engine area. There is a 18 second delay (speed of sound delay) due to the distance and altitude of the explosion. Question: How did this video operator know to have his camera running just prior to the missile explosion? How many people run their camera in the sky looking for an airplane cruising at altitude so high that most are not visible to the human eye? Note that the pilots are maintaining wings level, the airplane and burning wing still intact, in what appears to be an uncontrolled descent from 33,000 feet when the video ends at 1 minute 19 seconds.

Mish comment. I am not sure if I can make out everything David says, or if it is indeed flight 17, but it is an interesting clip.

Update From Jacob Dreizin

Hello Mish

This whole thing is a mystery of no lesser magnitude than that other Malaysia Airlines flight that disappeared in March. The true picture is even foggier than most people realize, with many questions unanswered.

Main Questions (7)

1. For unknown reasons, the flight diverted or was diverted from its usual course to fly smack over a tiny patch of land---of roughly 5000 square miles, or the size of Connecticut---controlled by pro-Russian rebels. (In fact, the 777 went down a few miles from the geographic bottleneck where three desperate Ukrainian brigades are trapped between the rebels and the Russian border.) Why? And if this airspace had been closed by Ukraine (on July 8th), why was that closure never registered with international aviation authorities or coordinating bodies?
