Answer 1

Apparently not in modern planes designed to do so. But after WWII there were more than a few people killed in old prop planes doing high speed dives and also people killed in early jets. Elevator control loss was the big issue and once in a dive you couldn’t get out. Soon after they got these early design issues figured out.
