yakker,
you may have done the "exercise" but you have not done it under certification requirements and they are way more strict. You can't have people climbing over the seats, etc. Can only climb over the seats if their is luggage in the isle.
We are also not talking about being on fire here. We are talking about the test. There will be no fire.
Also, the Cranfield test bed is just over half the height of the actual A380 height so next time you are up there think about what it would be like from double that height.
I never said the A380 would not be a success. I only pointed out there is significant tests that the A380 may have trouble passing. In this test, somebody may actually be maimed for life or killed.
