On 29 October 1970, while on passage from Las Palmas to Dakar, QE2 diverted from course at 1236 hours to render assistance to an engineer officer injured on the SS Cerinthus of the Hadley Shipping Company, London. The fifth engineer, David R G Senior, had suffered second-degree burns on his hands and face and was in critical need of expert medical assistance. QE2 reached the Cerinthus at 1332 hours and the lifeboat away by 1350, returning with the patient by 1422 hours, after which QE2 resumed full speed and the lucky man received the medical care his wounds required.
