There is a modicum of truth in letting the stick go forward when the stick is against the rear stops and your subsonic aircraft continues to pitch down.
Rather than make a big hole in the ground as you haul back on the stick, letting it go forward results in going under in a controllable bunt. Then when you get up the other side a roll from inverted will have you smiling and supercharged with adrenalin.
Was about to exercise this option in a Vulcan when flying to the corner of the envelope. Pitch down persisted whilst supersonic until we reached the vertical. At that point some control returned as Mach number reduced together with increasing IAS, minimum engine thrust and speed brakes beyond their normal deployment speed. By then crew had very tight harnesses in preparation for the bunt which soon became unnecessary.
