has a 744 at gate D-5 (if I recall correctly) they had what looked like a cherry picker that the marhsaller stood on to guide the plane in. The might use it at some other gates and for 772s as well. Several years ago, I was waiting for my flight at that gate and they mistakenly parked a 744 at the 742 mark so the incoming passengers had to wait for the plane to be towed to the correct mark in order for the jetway to reach the door.
"Temporary" Terminals C and D will probably celebrate their 25th birthday before they are replaced. This is just another reason why they should be replaced sooner. These are my least favorite terminals at a UA
hub. Maybe I should take the bus to Terminal G to make me feel better about C and D.
