Are they asking for a reason for the diversion? Or stating there's a rare chance to see an A340-600 at EGCC?
I would suspect it is a bit of both, Virgin A340's are not that thick on the ground up here, plus a bit of healthy curiosity.
Not really deserving of such an aggressive response really.
Find out a bit more as to why it diverted and then post it, it might be more interesting than it is so far.
I suspect that was the hope/intention of the original poster.
