I wonder what altitude the cabin finally reached. It is the descent, asa much as the climb, where ear problems can occur. A few decades ago there was an Air Europe B757, out of Bangor I believe. They decompressed at crz level. During the emergency descent there were numerous complaints amongst pax & CA's of ear damage/problems. I don't know what the cabin climbed to. If the cabin climbs to crz level, or above 25.000', and then descends at 6000fpm there is a strong chance of ear drum problems.
