It's a 767. Definitely mechanical if it's delayed that long. If not then the crew must be timing out.
Will edit this post once I find the ship on FlightAware. DL.com is saying that this is a modded 767 (searched ATL-ZRH on flight status instead of putting in 66 as the flight number) and it still showed there those icons.
EDIT: It's N154DL. 3P6-er.
