Anybody have an idea about this one?:

I assume maintenance or something but I’ve never seen a DL 767 at RDU. Would they even have the capability of servicing one? or GSO for that matter?

TIMCO is on the field at GSO, they have 757 and 767 in often, I have seen one or two 777 in there. I don’t know much about TIMCO but have seen several United 757, and 777 in as well as Tomsonfly and DHL 767’s. I know RDU has an American Airlines flight to London Heathrow daily, I believe they are using a 767-300 for it now but I used to see an AAL 777 in some. Like I said I don’t know a whole lot about it but hope this helps.
