Well, let's see if they release footage from the Mandalay Bay cameras to clear all that doubts.
Not likely. They eventually released like 3 frames of footage of the plane that hit the pentagon.
Maybe we'll get lucky and get 4 frames from Mandalay Bay in 10 years or so.
Or ya'know, they'll hire a look alike actor, reenact the scene, retcon the dates/times on the security footage, etc.. etc.. lol
