A kobrát meg tudja csinálni a sima 29-es thrust vectoring nélkül.

when performing a maneuver like Pugachev's Cobra the aircraft will 
stall as the nose pitches up and the airflow over the wing becomes 
separated, but naturally nose down even from a partially inverted 
position, allowing the pilot to recover complete control.

The Cobra, as performed by non-thrust vectoring aircraft, still 
depends on the aircraft moving through air; however, it does not 
involve the aircraft's aerodynamic surfaces and normal laminar 
airflow, but rather the whole airframe as a solid shape travelling 
through air, and its center of gravity in relation to the thrust 
vector. Being performed under conditions far beyond normal 
aerodynamic control and well into a stall without thrust 
vectoring, this is a form of passive supermaneuverability, 
possible because of aircraft design rather than thrust vectoring, 
which provides a way to actively control the aircraft well outside 
of the normal flight envelope.
