The Fleetwings Model 36 was a plywood skinned aerial target which was given the military designation PQ-12A. It was powered by a Lycoming O-435 of 225 hp and could be manually flown for testing & evaluation when designated as the YPQ-12A. Two examples of the YPQ-12A (41-39051 plus another) are in the background. A protrusion hanging down from the right hand wing, as seen here, housed a TV camera that fed images to a mother-ship for remote guidance to intercept an enemy aircraft. Another photo taken at the same time as this one shows the cover off and a 500 lb bomb in the pilot's position. In October 1943 the aircraft successfully downed a test drone over the Muroc Bombing and Gunnery Range. Photo from: William Engle via Tim Martin

More Harvards of No 20 Service Flying Training School. Cranborne sounds like a very English training airfield, doesn't it, but it was in Rhodesia - one of the places where Allied aircrew could train for the war in peace. EX180 later to South African Air Force as 7050. Photo from: Imperial War Museums

The RAAF took delivery of ten A-25As before cancelling an order for 140 more having deciding dive bombing was outmoded. A69-29 was one of those affected by the cancellation and was never delivered to Australia. It was eventually handed to the US Marines . Only one RAAF A-25 entered service and that was for testing. The 10 were handed back to the USAAF in 1945. Photo by: Hans Groenhoff / Smithsonian Institution

41-7746 was sold in Italy as I-PALU after the war. The back of the photo says it was taken in Italy, with Casablanca pencilled in. The presence of French aircraft discounts Italy. Both C-47s shown were based at Oran Tafaraoui, which was also a base for A-20s, P-39s and P-38s as seen in the background. A photo of P-40s at Casablanca at this time showed arched hangar roofs, not pitched as in the photo and the proximity of the mountains fits Oran better than Casablanca. However this is not a certainty and open to correction. Photo from: National Archives at College Park, Maryland

Ex CF-BMU donated to he RCAF in November 1939. Returned to CF-BMU in April 1945. The colour of this aircraft is not known. Photo taken on orthochromatic film which can make yellow look very dark and red look black. Photo from: Library and Archives Canada

Rollout of Frank Piasecki's PV-2 helicopter. According to the Vertical Flight Society, P-V Engineering Forum started in 1937 Callowhill Street in Philadelphia. A modern building now stands here but this would be the back side of the house, on Shamokin Street. The PV-2 first flew on 11 April 1943. The photo is dated October 1943, presumably in error.

One of the 10 DH82C-2 Menasco Moth Is built. They were followed by 125 DH82-C4 Menasco Moth IIs. The use of Menasco engines was in response to a shortage of Gipsy Majors. 4836 was disposed of in 1946. Photo from: Library and Archives Canada

A sad end to a famous aircraft...Following the loss of their Avro X VH-UMF 'Southern Cloud', Australian National Airways Ltd. (ANA) abandoned their interstate services and went into liquidation. C.T.P. Ulm, one of the principals of ANA, purchased Avro X VH-UMI 'Southern Moon' from the liquidators and had it rebuilt in highly modified form for use on route-proving and record-breaking flights. The aircraft was re-registered on 16 June 1933 as VH-UXX Faith in Australia. It's seen here in 1943 in a corner of Townsville/Garbutt aerodrome, rotting away. (CAHS/Stanley Brogden collection)

Beautiful study of Cessna's 'Bamboo Bomber', the aircraft that bomber pilots learned their trade on, although the UC-78 model was a light transport. Photo from: Nederlands Instituut voor Militaire Historie

Wartime photo of the airstrip at Mareeba in North Queensland. Built in 1942 as a base for B-17s. This photo likely taken in 1943 when P-38s from the 8th FG, 80th FS were stationed there. The CW-22 in the foreground is probably one of the Dutch aircraft diverted to Australia after the fall of the Dutch East Indies. Wartime Mareeba had two runways and an extensive network of taxiways. One (sealed) runway remains in use today. Photo from: State Library of Queensland

This AT-11 was ordered by the NEI air force and was to have been A-14, but delivered to the Royal Netherlands Military Flying School at Jackson with the serial 42-3070, based on the c/n. To the USAAF, 42-3070 was a B-17. The strange serial is clearly visible on the port side of the nose in another shot. In the background here are P-39 Airacobras in US markings, including 42-18885. Upon the closure of the school in February 1944, the Kansan went to the USAAF, becoming 44-72016. Later PP-CCF with Cruzeiro do Sul; crashed on 15 November 1957. Photo from: Bodo Sandberg collection

This was the sole XC-53A, distinguished from the standard C-53 Skytrooper by experimental fitment of full-span slotted flaps. These are visible in this shot, extending almost to the wing tips. It was later converted back to standard C-53.
