Hold your hand flat, like a wing, and stick it out of the window of a moving car (without letting people think you're signalling a turn). You can feel the air pushing your hand up or down as you adjust the angle of attack.
Look at the strange attitude of the fuselage here because the pilot has had to keep the wing angle of attack the same in space, but reversed relative to the plane, the green line shows the horizontal, but the black line is where the horizontal normally lies when the plane is flying the right way up. If the pilot had kept the fuselage nearer horizontal, as it is when not inverted, the wings would have been pushing the plane toward the ground.
