In a promotional video for the Paris 2015 airshow, this video was released promoting the new Boeing 787's near vertical takeoff capability. Whilst highly impressive, I was wondering if there is any practical benefit or advantage of such an aircraft being able to perform this manouevre?
If there is no benefit of being able to climb at this angle of attack, then why was this aircraft designed with such a capability. But if the 787 wasn't designed to intentionally perform this, then does this mean other Boeing aircraft can do this? And if other aircraft can do this, then why hasn't this manouevre been marketed in such a way before?
In other words, why even bother to design an aircraft capable of this, if it serves no real benefit? And why market the aircraft as being able to do so in the first place?
