The MiG-29M OVT is a 29M equipped with vectored-thrust engines and digital fly-by-wire controls (the nozzles at the back are articulated to 15 degrees of motion in any direction) and so the aircraft is capable of some very agile high angle-of-attack maneuvers, like backflips...a highlight is where the aircraft is climbed vertically to a standstill (an old MiG29 showstopper) but then is flipped on it's back, and freefalls inverted.
