Photo of Bluey Truscott. Squadron Leader Keith William (Bluey) Truscott was regarded as one of Australia’s most well known WW2 fighter pilot aces. He was born on the 17/5/1916 and died over Exmouth, Western Australia on 28/3/1943 in an Aircraft accident whilst on duty. He initially trained under the Commonwealth Empire Training Scheme In Canada at the beginning of WW2, and later on was posted to Number 452 Squadron England where he flew Spitfires over Europe. He was awarded the distinguished Flying Cross in 1941 for his Air action and bravery. In 1942 he was further awarded the DFC Bar for further outstanding Air action and bravery. He returned to Australia and commanded number 76 Squadron who undertook duties in Papua New Guinea, specifically Milne Bay. When with 76 Squadron they largely flew Kittyhawks. There is a club named after SQN LDR Truscott, called the Truscott Club, at Airforce Base Darwin. There is also a decommissioned WW2 Airfield in the Kimberley’s called after him ( Truscott Air Base). Truscott has more recently been called Mungalu-Truscott Air Base as it is now owned by the traditional people of the Wunambal Gaambera. The Airfield is now used for commercial and private flying and is heritage listed under the National Trust of Australia (W.A.) due to its historical significance relating to WW2 and the remaining artefacts that are still in place presently. Bluey Truscott was also a well known Australian Rules Football player prior to WW2 having played for Melbourne.

A porthole, sometimes called bull's-eye window or bull's-eye, is a circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armoured vehicles, aircraft, automobiles (the Ford Thunderbird a notable example) and even spacecraft. On a ship, the function of a porthole, when open, is to permit light and fresh air to enter the dark and often damp below-deck quarters of the vessel. It also affords below-deck occupants a limited view to the outside world. When closed, the porthole provides a strong water-tight, weather-tight and sometimes light-tight barrier (not in the case however). A porthole on a ship may also be called a side scuttle (side hole), as officially termed in the International Convention for the Safety of Life at Sea. This term is used in the U.S. Code of Federal Regulations. It is also used in related rules and regulations for the construction of ships. The use of the word "side scuttle" instead of "porthole" is meant to be broad, including any covered or uncovered hole in the side of the vessel. This porthole is a useful demonstration of naval technology to give people an insight into life at see. Small windows such as this example could be all people would see on long see voyage across rough seas. Commanding officers scuttle made of brass with glass opening windowmaritime technology
