This is more of a head-on video.

This is not meant to incite an argument or start questioning or building opinions...but I am genuinely curious (as I have no knowledge here) but aren't there briefings on looping patterns and tower control for these shows or is it more flexible?
Separation & situational awareness are obviously high priorities at large warbird gatherings like this, something went amuck and speculation is pointless at this time.
I have seen "flexible" shows when I was a kid, including shows with no tower control at all, in fact no tower present. This could not have been one of those [if they are even allowed anymore, I'm talking late 70's], with major performers at a large city airfield. Typically, tower closes off airspace at a predetermined time then hands off control to an "airboss" when showtime starts, who uses his own frequency to control the aircraft, and has complete operational control over all performing aircraft for the entire duration of the show from takeoff to landing. These "bosses" actually travel the country controlling shows, not sure how many of them there are but I would guess the numbers are low.
Airboss channel can easily be monitored on a scanner, I have been listening in for years at shows. Never really thought about it before but I presume the airboss concept was/is to use guys with alot of airshow experience to control this highly specialized and unique airflow, as an average air controller would not be well versed controlling a dozen or more aircraft making continuous passes. Also minimizes potential for miscommunications since they are all on a single control frequency. 1 guy, 1 freq and all performers are glued to that freq and conduct all traffic through it [The only exceptions to airshow airboss control are demo teams like the Blue Angels. They use their own controller, and you can hear them hand off and hand back control during the progression of shows] Not a factor here, just added for insight.
When the last performer lands and the show is over, airboss hands airspace control back to the tower, tower cancels all airshow restrictions, and the formerly very active airboss frequency goes mute until the next airshow.
Very skilled and experienced, but not perfect, I have heard them get overwhelmed and make mistakes, probably the nature of the game and would happen no matter what system they used. Cannot underrate the difficulty of controlling so many aircraft all over the sky, some ingressing, some egressing, some still taking off, some perhaps requesting to land, with some identical types adding complexity [ie: Cannot have a call sign of "Mustang" as they would for a single ship if there are more than 1 Mustangs performing - In that case they would likely go Mustang 1, Mustang 2 ect] ,, But unless they are doing all formation passes, hes got to be sure he is talking to the right Mustang. I think the average tower controller would not care for that task, to laymen like us it would be unimaginable. They've got to be authoritative but laid back, easy going yet harsh when they need to be - Their commands must be complied with immediately and without question. The flow of the show and, more importantly, lives and machines depend on them having complete and correct 3D situational awareness, and making the right calls at the right time.
No one at that ill fated show would have had a better technical overview into what went wrong here than the airboss, and his input will be critical to the investigation.
As far as briefings prior to the show, maybe someone with more direct knowledge than me can chime in, but yes certainly every pilot performing would be aware of his routine and coordinate with others, most shows have full practice sessions a day and sometimes 2 days prior to the show, though for obvious reasons sometimes not all aircraft are present for the practice [late arrivals] These practice sessions BTW are a joy to watch, sometimes better than the actual show, and often from vantage points that are closed off on show days.
