filter problems again?
They need to stop going to Iffy Lube.
It was a brake issue, pilots thought there would be brake trouble upon landing at DEN so they went back to IAH, landing was fine, no issue with the brakes, this reported by a passenger on board.
The aircraft was supposed to continue to NRT as UA 139, they will now turn the 787 from UA 138 and showing a 70 minute delay leaving DEN right now to NRT. Wow, they have got to get this thing figured out soon.
