Early Aviators

Can anyone tell me more about any of the following early aviators, please? They were definitely flying in the early 1920’s.

— Salvador Augusto Gomez
British National; Gibralter connection; served with the 3rd Dorsetshire Regiment; RAF service recorded at the National Archives in AIR 76/187. Marriage to Yvonne O’Sullivan-Beare in 1926.
Now identified as Salvador Gomez-Beare, of “Operation Mincemeat” notoriety. Nothing further required.

— Cesar Herraiz-Llorens
Spanish National and military pilot; in April 1923 he force-landed in enemy territory during the Berber uprising in Morocco, was captured and died in captivity. Does anyone have easy access to Spanish military and other records to discover more about his story?

— Nicholas Olechnovich
Russian National; known as Nicholas Nicholas; Mechanical Engineer; London Gazette references in 1924 and 1937; patent address in Reading in 1933.
Naturalised British 12 January 1937, when resident at 16 Oakfield Court, Kings Avenue, London SW4.
Born 23 January 1886, Yalta, Crimea. Married to Alexandra. Nothing further required.

In all three cases, other spelling variations are possible. The purpose of my enquiry is to establish a context or life story for them (date and place of birth, marriage, children, career, death etc.). However, all new information gratefully received.

Thank you very much.
