Here is an interview of Viktor Pugachev about this COBRA aerobatic maneuver.
Interview with Victor Pugachev - Vayu Sena
Nothing wrong with cool air show maneuvers demonstrating the capabilities of an aircraft, kind of similar to all those missiles and rockets and tank shells, artillery shells that are fired by the army to impress foreign customers.
AFs around the world should have their own space.
Some things are just amazing to see, like that big-big Russian helicopter (you know the biggest one).
Or that trident type maneuver that these combat planes do at high speeds.
As far as airshows go
That Mig-29 OVT is amazing bird, forget this COBRA, it can do (what seems to me from the ground perspective) very amazing things in the air.
I hope i get the opportunity to see it preform live.
