I remember seeing flight demos of the harrier at NASA Ames back in the '80's. They'd do the "bow", then rotate around, back to the audience, and point the nose up (sort of a reverse "bow"), and accelerate to full flight at that nose up attitude. Pretty impressive.
The coolest flight demo I ever saw at Ames, was the Harrier, the XV-15 (V-22 prototype), and the QSRA (Quiet Short Haul Aircraft) all flying together.
...oops, QSRA is Quiet Short-haul Research Aircraft.
