Still to be seen is whether the over-wing departing engine ruptured a fuel tank before the later explosion.
Design intent is that in an overload situation, the strut will fail in such a way that the engine goes over the wing instead of under, without rupturing the fuel tank. However that's all done by analysis - how it works in the real world will be interesting to find out.
Regarding windshear - many airports in the US have ground based windshear detection systems (Doppler radar based, IIRC) so ATC can warn approaching aircraft or even temporarily close down a runway. Why wouldn't a major airport like Dubai have a similar system?
As for passengers evacuating with carry-on luggage, how about creating a separate thread so you can re-hash all the arguments that get repeated after every ground evacuation without cluttering up the thread for those of us that want to discuss what actually happened? Maybe the mods can make it a sticky
