The Corvair was a GM automobile, made infamous by Ralph Nader's book "Unsafe at Any Speed."
You're thinking of the de Havilland Comet (or possibly the aircraft manufacturer Convair).
Hah!! Not even close. Thanks.
Airworthiness of the Corvair was also suspect.
That was the de Havilland DH 106 Comet. He is talking about the Chevrolet Corviar, which was a car and the subject of Ralph Nader’s book Unsafe At Any Speed.
