Just came across track Bravo with A-380 4,000 feet above us. Had to slow down our B757 for it to catch us. We got lots of pictures (collector items). Pilots said they had about 500 people on board headed for JFK, their fuel flow was 7,000 pounds per engine (X4). Funny thing was a British Airways B747-400 caught up with it circled around it a coupled times getting pictures and then went back to normal cruise speed and blew the doors off it. 40 year old technology airplane kicked it ass. Why would anyone want this slug?
