For the sake of argument, lets say that this is not a lens flare, and take away the UFO nonsense to try to find a more realistic scenario that could
fit what is being observed.
As the asteroid enters the Earth's atmosphere, it has already started to fragment due to stress. Directly behind the main mass are smaller pieces
(albeit, still quite massive) that are trailing it. The main mass hits the atmospheric wall and probably slows down to half it's speed in a second.
The fragments behind it are shielded from the terrific forces the main mass is now subjected too, since they are riding in it's wake, much like a car
behind a semi-truck.
As soon as the main bolide starts to lose it's cosmic velocity, the pieces behind it ram directly through it , further breaking up the main bolide.
As a result, there is much more surface area of the fragments now in direct contact with the atmosphere and a second later, Boom!... they all succumb
to the thickening atmosphere as if they hit a brick wall.
It is just a fanciful scenario, but see how much better it fits the observation than lens flares and UFO's ?
