Is it just me or are you actually looking to stir **** in every single topic that comes up when you search for "Airbus"?
Ontopic: Airbus is already experimenting with other systems to evacuate passengers from the upper decks that are safer than the traditional inflatable slide, like the ones used on oil rigs and some high buildings to get people off safely from much greater heights.
I saw it on ZDF the other day on a docu about the A380... see if you can find it, it's bound to be in their mediathek on
www.zdf.de somewhere. Pity if you can't read/understand German
