I want to watch the in-flight video of someone doing a roll while keeping
his/her head aligned with the horizon.

Military style - according to an old P-51 combat WWII pilot.

They were taught to pick a point on the horizon and fly around it as a
training exercise. He flew me through several with virtual perfection.
Say a barrel roll to the left. With speed, turn about 45 deg. to the right,
pulling the nose up some 20 deg. and start the roll to the left. Rudder and
stick control as required to hold the nose equidistant from the point all
way around. Past vertical to knife-edge and begin right rudder for
coordinated turn 45 degrees back to straight and level. The point is
straight ahead. Obviously, he stared straight ahead thruout.

This is approximate, because after about 100 tries I never came close to
getting it right.
