Even flying a long haul at high altitudes exposes all of us (and our gadgets) to fair amount of radiation; the further you are from the equator, the higher the exposure too.
I agree that it seems unlikely that environmental exposure on board caused your problem - but scientifically speaking, your experience doesn't constitute 'proof' either.
Not disagreeing by any stretch, just injecting a little perspective for argument's sake..

It's extremely difficult to shape electromagnetic fields in such a way that only one RAM chip or bank would be affected. If external fields were the culprit, it's likely that there would be extensive damage. One would have to place a strong magnet practically on top of the chip in question for this to occur.
