21:31:07 - Mike Wire notices flare like object rising over house and arcing to left. In the next 8 seconds many more people notice streak, firework, etc.
So let's focuse once again on your allegation that approximately 26 seconds elapsed between the Initiating Event and Massive Fireball explosion in the following two times/places/events you have also alleged -
20:31:13 - ~13,840 ft. - Initiating Event, includes bright white Ordnance type explosion. (IE)
20:31:39 - ~7,000 ft. - Massive Fireball explosion. (MF)
- and compare that to the following:
"That one eyewitness is Michael Wire, a machinery expert who was working on a new drawbridge on Beach Lane, a road running from Westhampton, Long Island, to the beach. Wire's FBI report says that standing on the bridge, looking toward the beach, he saw a white light just above the rooftop of a house about 900 feet away, ascending from the ground at about a 40 degree angle. It "sparkled" and he thought it was fireworks. It "zig zagged" as it traveled upward and was going south-southeast when it "arched over" and disappeared from view. Two or three seconds later he saw an orange light that appeared to be a fireball in the sky about half a mile away. It was falling at about a 30-degree angle, with a fire trail burning behind it."

Note that the "two or three seconds is almost exactly the same as witness Meyer's 3-4 seconds and witness Brumley's 1-2 seconds but in all 3 cases over 20 seconds less than the 26 seconds elapsed time between the IE and MF you have alleged.
The "shootdown" scenario alleged in your sequential timeline is entirely dependent on whether the elapsed time in question was about 1-4 seconds or the 26 seconds you have contended.
It appears that NONE of the "shootdown" website authors have endorsed your sequential timeline by including it in their sites. However, it is now here.
