The Barnes Wallis Moth Machine was a modified microlight aircraft designed for collecting moths and other flying insects over rainforest canopies. The core machine was a Pegasus Q microlight aircraft. Modifications for moth catching were designed by Charles Cockell and implemented by a team of engineers at Enstone Airfield, England. [1] [2] [3]
The machine was test flown in Oxford by Charles Cockell and then flown over the rainforest canopy in Sumatra, Indonesia [4] in 1993 by Cockell in an effort to catch moths to catalog the diversity of moths in the rainforest as part of a biodiversity study of the Kerinci Seblat National Park. The machine had several modifications for moth catching: 1) Ultraviolet lights under the front of the aircraft for attracting moths during systematic sweeps of the forest, 2) A moth catching device consisting of an inverted funnel with a pleated butterfly net at the end for trapping moths scooped during flight, 3) A forward facing one million candlepower lamp to avoid trees whilst flying during dusk, 4) Two one million candlepower lamps pointing downwards at an angle to estimate height above the forest canopy, using a similar principle to that adopted for night flying during the 617 Squadron Dams raids in World War II and developed by Barnes Wallis (for whom the machine was named), 5) Infra-red night vision system for improving visibility during night time moth catching, provided by 617 Squadron and worn by the entomologist pilot.
The Patrons of the expedition were Susannah York, David Bellamy and 617 Squadron. Corporate Patrons were Barbour, BP, Pilkington and Containerway.
The machine was flown for several moth catching sorties over the rainforest, north of the Sumatran town of Bengkulu during July 1993. Moths were also caught using UV lamps on the ground.
During the expedition, whilst attempting to land the moth machine in a rainforest clearing, it clipped the top of a tree and crashed, destroying the machine, although Cockell escaped uninjured. [5]
The Bristol Blenheim is a British light bomber designed and built by the Bristol Aeroplane Company, which was used extensively in the first two years of the Second World War, with examples still being used as trainers until the end of the war. Development began with the Type 142, a civil airliner, after a challenge from the newspaper proprietor Lord Rothermere to produce the fastest commercial aircraft in Europe. The Type 142 first flew in April 1935, and the Air Ministry, ordered a modified design as the Type 142M for the Royal Air Force (RAF) as a bomber.
Ultralight aviation is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight".
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same era.
The Dam Busters is a 1955 British epic docudrama war film starring Richard Todd and Michael Redgrave, that was directed by Michael Anderson. Adapted by R. C. Sherriff from the books The Dam Busters (1951) by Paul Brickhill and Enemy Coast Ahead (1946) by Guy Gibson, the film depicts the true story of Operation Chastise when in 1943 the RAF's 617 Squadron attacked the Möhne, Eder, and Sorpe dams in Nazi Germany with Barnes Wallis's bouncing bomb.
Geoffrey Leonard Cheshire, Baron Cheshire, was a highly decorated Royal Air Force (RAF) pilot and group captain during the Second World War, and a philanthropist.
Operation Chastise, commonly known as the Dambusters Raid, was an attack on German dams carried out on the night of 16/17 May 1943 by 617 Squadron RAF Bomber Command, later called the Dam Busters, using special "bouncing bombs" developed by Barnes Wallis. The Möhne and Edersee dams were breached, causing catastrophic flooding of the Ruhr valley and of villages in the Eder valley; the Sorpe Dam sustained only minor damage. Two hydroelectric power stations were destroyed and several more damaged. Factories and mines were also damaged and destroyed. An estimated 1,600 civilians – about 600 Germans and 1,000 enslaved labourers, mainly Soviet – were killed by the flooding. Despite rapid repairs by the Germans, production did not return to normal until September. The RAF lost 56 aircrew, with 53 dead and 3 captured, amid losses of 8 aircraft.
Wing Commander Guy Penrose Gibson, was a distinguished bomber pilot in the Royal Air Force during the Second World War. He was the first Commanding Officer of No. 617 Squadron, which he led in the "Dam Busters" raid in 1943, resulting in the breaching of two large dams in the Ruhr area of Germany. He was awarded the Victoria Cross, the highest award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces, in the aftermath of the raid in May 1943 and became the most highly decorated British serviceman at that time. He completed over 170 war operations before being killed in action at the age of 26.
The Fairey Firefly is a Second World War-era carrier-borne fighter aircraft and anti-submarine aircraft that was principally operated by the Fleet Air Arm (FAA). It was developed and built by the British aircraft manufacturer Fairey Aviation Company.
The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer aircraft. In addition to the type's principal use for ab initio training, the Second World War had RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers.
The Vickers Wellesley was a medium bomber that was designed and produced by the British aircraft manufacturer Vickers-Armstrongs at Brooklands near Weybridge, Surrey. It was one of two aircraft to be named after Arthur Wellesley, 1st Duke of Wellington, the other being the Vickers Wellington.
The Indian nightjar is a small nightjar which is a resident breeder in open lands across South Asia and Southeast Asia. Like most nightjars it is crepuscular and is best detected from its characteristic calls at dawn and dusk that have been likened to a stone skipping on a frozen lake - a series of clicks that become shorter and more rapid. They are sometimes spotted on roads when their eyes gleam red in the spotlight of a vehicle. There is considerable plumage variation across its range and can be hard to differentiate from other nightjars in the region especially in the field.
A bouncing bomb is a bomb designed to bounce to a target across water in a calculated manner to avoid obstacles such as torpedo nets, and to allow both the bomb's speed on arrival at the target and the timing of its detonation to be predetermined, in a similar fashion to a regular naval depth charge. The inventor of the first such bomb was the British engineer Barnes Wallis, whose "Upkeep" bouncing bomb was used in the RAF's Operation Chastise of May 1943 to bounce into German dams and explode underwater, with an effect similar to the underground detonation of the later Grand Slam and Tallboy earthquake bombs, both of which he also invented.
Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War.
No. 10 Squadron is a Royal Australian Air Force (RAAF) signals intelligence (SIGINT) squadron based at RAAF Base Edinburgh, South Australia. It is part of No. 92 Wing RAAF. The squadron was formed in 1939 as a maritime patrol unit. It saw active service during the Second World War, conducting anti-submarine operations and patrols from bases in the United Kingdom until it disbanded in late 1945. It was re-formed in Australia in 1949 and since then has contributed to Australia's East Timor intervention, and has been deployed to the Middle East as part of the War on Terrorism and the 2003 Gulf War. Most recently it now has a signals intelligence mission.
No. 619 Squadron RAF was a heavy bomber squadron of the Royal Air Force during the Second World War, flying Lancaster bombers from bases in Lincolnshire.
No 36 Squadron of the Royal Flying Corps was formed at Cramlington in 1916 and was disbanded for the last time in 1975.
Beccles Airfield, also known as Beccles Airport or Beccles Aerodrome, is located in Ellough, 2 NM southeast of Beccles in the English county of Suffolk. Built during the Second World War, it has operated as a heliport servicing the North Sea oil and gas industry and currently operates as a base for private flights, flight training and parachuting.
Charles Cockell is a British astrobiologist who is professor of astrobiology in the School of Physics and Astronomy at the University of Edinburgh and co-director of the UK Centre for Astrobiology.
The de Havilland Mosquito was a British light bomber that served in many roles during and after the Second World War. Mosquito-equipped squadrons performed medium bomber, reconnaissance, tactical strike, anti-submarine warfare and shipping attack and night fighter duties, both defensive and offensive. Mosquitos were widely used by the RAF Pathfinder Force, which marked targets for night-time strategic bombing. Despite an initially high loss rate due to low-level daylight attack operations, the Mosquito ended the war with the lowest losses of any of the aircraft types in RAF Bomber Command service.
Lawrence Seymour Goodman was a British airman and bomber pilot, who served in World War II. He was the last surviving wartime pilot of the No. 617 Squadron RAF which carried out Operation Chastise, although he did not join the squadron until after the operation.
