and to add to the win box issue, heard yesterday that there is a further issue with the 787 Titanium Bolts reacting with the composite material used and causing corrosion - anyone else heard this??
I'm no expert on metals chemistry but with titanium's corrosion resistance and general difficulty to get it to react with anything if not heated, I doubt it very much. In fact I'd even go so far as to give a tentative "I think that's bollox" to that rumour.
