The guy's using English as a foreign language- how would your questions look in Arabic chaps? Good on him- he made his meaning known, and deserves a sensible answer. What bugs me are the English people here who have completed umpteen years of education (that I paid for) and still can't differentiate between there, their or they're. Now that's an offence!
So q80airbus- these composites are carbon fibre. Carbon fibre has been in service for years, mainly in flight controls. It's qualities are well known in lightning strikes. This aeroplane will have more than any other civil transport. The FAA would only certificate this aeroplane if it was completely confident that it was safe and the damage and lightning repair damage qualities were well known. As pointed out, military aeroplanes are ahead of civil in this area, so it is not an unknown quality. Also, people have full trust in Boeing knowing what they're doing- they did after all produce that work of art, the B747!
