While Traveling to Balto on I-83 yesterday 06/22/07 I saw a wideload truck hauling a horiz stab assy. It was a t the Pa welcome ctr parked heading North. It was the whole assembly both sides with the trim jackbox between them. Does anyone have an idea what this plane this part goes to and where the shipment was headed?? Bombardier wouldn't haul something like this up to their factory, I mean its 500 or so miles away from where the part was. Thats all I can think of as to what the part belonged to. I should have stopped and chatted with the driver but I was in a rush.
