Aircraft on display at No. 1 Aircraft Depot

No. 1 Aircraft Depot (No. 1 AD) was a maintenance unit of the Royal Australian Air Force (RAAF). Formed in July 1921 at RAAF Point Cook, Victoria, it relocated to RAAF Laverton in March 1926. In its early years, the depot serviced aircraft and other equipment, trained maintenance staff, and supported survey flights in Australia and the Pacific region. No. 1 AD's strength increased from 350 staff in the 1930s to more than 2,000 during World War II, when it assembled, tested and repaired aircraft such as Tiger Moth trainers, Spitfire fighters, and B-17 Flying Fortress heavy bombers. After World War II, No. 1 AD introduced the first jets into RAAF service. In 1961, it ceased airframe maintenance but continued to service aero engines. By the 1970s, the depot's focus was ground-based equipment, though it still handled some aircraft components. No. 1 AD was disbanded in December 1994; at the time of its disbandment, it was the oldest RAAF unit in continuous operation. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
