The F-100 had an adverse yaw problem - worse on takeoff. With a swept wing, if you use aileron at low speeds, the wing with the down aileron creates more lift but also more drag, and as that wing gets pulled back, its swept angle causes it to lose lift while the other wing is advancing and getting more direct airflow, so it has more lift. The result is that if you try to roll left, the plane actually rolls right, and the more you push the stick over to "correct" that, the problem gets worse. You can actually snap roll just a few feet above the runway. And that's fatal. F-100 guys had it drummed into them to never use aileron on takeoff, only rudder.
The "Saber Dance" video happened when the pilot got too slow, pulled the nose up and immediately got "behind the power curve" where there simply isn't enough thrust to overcome the near-stalled drag. In that realm, the adverse yaw threat also appears, and you are essentially doomed from the instant you haul back on the stick. As that guy was.
Thanks for sharing!
