Its chief engineer from 1935 to 1959, he served on the RAAF's Air Board for a record seventeen years and was credited with infusing operations with new standards of airworthiness. Starting as a Royal Australian Navy cadet, he transferred to the Air Force in 1923. He inaugurated parachute instruction within the RAAF and made the country's first freefall descent from a military aircraft in 1926. Wackett rose to air commodore by 1942, assuming the role of Air Member for Engineering and Maintenance, then established the Technical Branch as a separate department of the RAAF in 1948. He was appointed Commander of the Order of the British Empire and Companion of the Order of the Bath. From 1960 to 1968, he was a member of the Australian National Airlines Commission, the parent of Trans Australia Airlines. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
