I thought it was a broken vein in the brain - speech slurred after hours
and not talking well. Now it seems like a cop out - but it might
have been a blood clot that was dislodged in the heavy slam on the plane.

Sounded like the pilot put the nose wheels down first! Both blew.
I'd suspect the altimeter in the plane or the radar glide path....

Normally, the heavy center mounted wheels take the impact, and most of
the time, a kiss then slowing down by air brakes dropping the nose.
