Can anyone tell me, why do you need airbrakes at all? Just raising or lowering nose kills ultimate amounts of velocity even in upper atmosphere, so you can just descend with engines off at 45 degrees down, raising nose to 45 deg climb for speed kill, and evade getting red at all. My main problem with landing is that without turning engines on it's easy to kill all horizontal velocity in a hundred meters above the ground, resulting vertical fall with tens of m\s, breaking gear and possibly dividing aircraft into to pairs, not allowing me to ride it to the runway. Anyway, killing speed is easier than ever even without airbrakes.
