aviate1138,
Do you know PAX evac certification requirements? Since there was no A380 for Cranfield to use to test, their results can only be speculative at best. How many 55+ women were involved in the test? How many small children and babies? Was there baggage spilled in the aisleways? I bet they planned and coached the people who did the test, your not allowed to do that when it is for real.
How quick do you think you would be to jump off a 4-5 story building onto a slide knowing that the big heffa with heals is right behind you?
Ask somebody you know at Airbus in France, I heard it was quite the story.
Even Airbus knows people are going to be scared because they are putting a "horizon" barrier so people can't see how high up they are. Since nobody runs 30 MPH and that is the speed you will be coming off at pretty much everybody will face plant. One after the other on top of the people in front of them.
