#1 - Amen to Owain's post.
#2 - Some of the contributrors here may benefit from being reminded that lift & drag are defined as the aerodynamic forces perpendicular & along, respectfully, to the free airsteam, NOT the airframe.
As far as the THS is concerned, with the airplane 'falling' @ ~60deg AOA (e.g) drag would contribute more pitch down moment than lift.
