With a P-70 it was mandatory to have patience & thrust vectoring to get out of the inverted harriers and it wasn't quick to get out. A P-120 & vectoring will push it out immediately. Without vectoring on a P-70 and even on bigger engines, it can be a long wait for the nose to pitch out of the situation. Once I had to use the rudders to slice into a spin to get the nose to break below the horizon. Never tried the airbrake.
