Well, and not only that, why is it that we can see fire shooting from its bottom if this aircraft is supposedly heading to Phoenix?
You must have missed the memo! ;^) That's the sun reflecting off the bottom of a plane headed straight and level at very high altitude, although that same sunlight evidently missed illuminating the flat, level bottom of a supposend condensation trail stretching behind for hundreds of miles in the same manner. Fickle thing, a westerly sun.
And besides, it's not Phoenix anymore, it's Ontario Airport, about 50 miles due east of the coast of Santa Monica, where the camerman possibly was located (though where the helicopter actually was has yet to be determined). AND as it happens, that particular flight TO Ontario, according to yeoman's work by a savvy FReeper, WOULD have been at a very high altitude (surprising, but true) heading southerly, to make sudden dramatic drops in altitude (it was a cargo plane, not a passenger jet, so it could get away with it) on turnaround heading north-east, well over land, to be able to land at Ontario Airport.
Then again, I think THAT flight has now been abandoned for yet a THIRD "proven" commercial airplane flight, though I'm not sure which one. I've kind of lost track!
