So to be clear, the Snowbirds don't fly practice EFATO PFLs? If not surely they must brief to only leave above a certain height and speed, not start turning.
All very odd; jet enters what looks like an uncoordinated turn, spins to the right through a full rotation, and seems to briefly (self?) stabilise as the crew leave. No smoke, flame or debris from the jetpipe before the pull-up, no change in engine note that I can hear.
