Salute!
I saw the video way back, and it was a quick roll into the tail of the Buff, but the thing did not get into what looked like a flat spin for some time.
The wing tip contribution to performance should still be a factor, just as the vortex we get on the Hornet, Viper and Rap and Stubbie from using the lex features.
What a loss, and glad we had the Black bird to do high mach research for another 2 decades.
