About the handle, sorry I can't say more than I already have.
My guess is that ua549 was one of the flights that got cancelled in Chicago last month due to "computer related problems".

I don't take kindly to moderation of any kind except in the context of deleting spam.

So when I find a thread missing... I'll just fight fire with fire... maybe start altering and abusing certian features on this site myself just to prove a point.
