'creamy' we are already well into that 30 yr RoR by half & by the time the idiots make a decision & complete the drome ready for Ops that 30 yr period would be well & truly gone like most of us here.
Aviation hasn't changed fundamentally since the 'Wrong Bros' started it all a little while ago, what we need is a new way of transporting the masses.
Aviation has stalled & for all of us involved in aviation today I doubt we shall see any change in that situation in our lifetime or the foreseeable future.
