Just chilled out watching the Megastructures TV program on designing and building the QM2. Program said that they avoided aluminum for the upper structure, even though it would save substantial weight and consequently allow the ship to be within its target width. It had been used on the QE2 but now that ship was prematurely coming to the end of its life due to aluminium fatigue.
Quick google showed this on a bike site: "You should be aware that aluminium has a limited life - aluminium frames usually have a guarantee of five years maximum as they fatigue"
Maybe ships and planes are under more stress than A2s hitting pot holes!!
And there was me thinking I could keep the car for ever ;-)
(well more than 10 years)
