Nerve impulses travel at about 120 m/s, max, and that's along long myelated runs. Cohering raw pain signal into the experience of pain takes at least 150 msec according to the best measurements we have on the topic.

The vertical speed of the plane alone at last reported speed indication exceeds the speed of neuron transmission along myelated nerve tissue. This impact event is mechanically impossible to feel.

Unfortunately, even at a descent rate of 30,000 feet per minute you've got a full minute to anticipate the impact before you don't feel it.
