Flight Lieutenant Ernest Melville Charles Guest DFC (1920 – 4 October 1943) was a Rhodesian-born Royal Air Force pilot of the Second World War. He was awarded the Distinguished Flying Cross in 1942 having flown more than 1,000 operational hours. Posted to South Africa as a flight navigation instructor, he was unhappy and got himself transferred back to England on operational duties. He soon went missing in October 1943 after taking on six Ju 88s while on an anti-submarine sortie.
