It was an air show demonstration
An airshow demonstration of what?
A demonstration to everyone how the seating pitch was greater than on other airlines?
The food was better?
They were the most punctual airline in the region?
They could low level bomb the arrival airport and bank away before the SAM's got them?
Being honest, large passenger aircraft do not do "displays" well. They do not do anything "sexy"
And the pilots should not try to!
