Hector Bertram Gray, GC, AFM (6 June 1911 – 18 December 1943) was an officer of the Royal Air Force, and a member of the British Army Aid Group, who was posthumously awarded the George Cross for "most conspicuous gallantry" in resisting torture after the Japanese occupation of Hong Kong in 1941.

[2] In November 1938 Gray, then a sergeant pilot with the RAF Long Range Development Flight, was acting as a radio operator/mechanic in one of three Vickers Wellesley bombers that flew non-stop for two days from Ismailia, Egypt, to Darwin, Australia, (7,162 mi/11,525 km) setting a world distance record.

Gray was awarded the Air Force Medal in recognition of the services he rendered to crews of the two aircraft on the long-distance record flight.

When the Japanese grew suspicious he was tortured and interrogated for six months but refused to divulge the names of fellow officers, such as Captain Douglas Ford of the Royal Scots, and Colonel Lanceray Arthur Newnham of the Middlesex Regiment.

He was executed by firing squad, with fellow prisoners, on 18 December 1943 and buried in Stanley Military Cemetery in Hong Kong.
