isn't it Cranfield in the UK which does evacuation time trials on various aircraft types? I believe they developed the 'model' by which these trials are conducted in other countries?
It would be interesting to see the results now if they added a 'person of size' element into the trials! Could aircraft still be evacuated in the time specified by the controlling authorities?
Good old visionary Airbus they saw all this coming, let's build the supersized A380!!
