At first glance, it's interesting, but, a fake . . .
I have seen a 767-300 on take off in Atlanta do this, though. It was loud as hell. I was a good mile away when it happened. Several Series of backfires or compressor stalls, and we thought the engine was exploding. Lots of Flame . . . We all stopped dead in our tracks and watched the aircraft do a slow climb (on one engine) and circle around for an emergency landing. Turns out, the engine was OK, but, the flight to Shannon, Ireland was cancelled.
Several Years Ago, I was out on the ramp and saw an L-1011 do the same thing on the number two engine . . . That woke everyone up . . .
Thanks, Dave . . .
