Canada's Gift To NASA

The Maple Leaf in Orbit

ï¿½ By a lucky coincidence, the Canadian government picked this time [1959] to cancel the Avro CF 105 Arrow, a supersonic interceptor, and Gilruth [head of NASA Space Task Group] acquired 25 experienced Canadian engineers.ï¿½

It is generally well known that the ingenious CANADARM manipulating device carried on all NASA Shuttle vehicles to launch and repair satellites and other spacecraft was designed and built in Canada by Spar Aerospace. The virtually faultless operation of the arm has been a major influence in the successful launch of a large number of important projects over fifteen years of Shuttle operations. However, less well known is Canadaï¿½s tremendous contribution to the United States space programs in the pioneering days of the late ï¿½50s and throughout the ï¿½60s and early ï¿½70s when the single-man Mercury, the two-man Gemini, and the moon-landing Apollo projects were being developed.

The cancellation of the Avro Arrow supersonic fighter project on February 20, 1959, initiated the breakup of the extraordinarily talented team of engineers at Avro Canada, a team that had put Canada at the forefront of world aviation technology with the design and development of such projects as the C 102 Jetliner, the first jet passenger plane to fly in North America, the CF 100 all-weather fighter, and the legendary CF 105 Arrow.

In the meantime, the newly formed Space Task Group at the National Aeronautics and Space Administration (NASA) facility at Langley, Virginia, led by Robert Gilruth, former Assistant Director of the National Advisory Committee for Aeronautics, was overloaded with urgent work on the Mercury space capsule design. At the time Gilruth was desperate to find experienced engineering personnel to develop the project. Gilruth had been involved in the wind tunnel and free-flight model testing of the Arrow models at Langley and the firing range on Wallops Island and was well aware of the unique capabilities of the Avro engineering team. He was quick to take advantage of their availability and made an arrangement with Avro to borrow a team of approximately 25 engineers to go to Langley and work on the development of Mercury.

The idea was to keep the ex-Avro engineers together as a team, with the intention of returning them when Avro sorted out the future of the company in the light of the Arrow cancellation. On the later demise of Avro Canada, the loan became permanent and the Canadian engineers were integrated into the Space Task Group, later contributing to both the Gemini and Apollo projects.

At the time of the Arrow cancellation, the Canadian team was led by the Chief of Design at Avro, Jim Chamberlin. His career provides an example of the type of Canadian expertise made available to NASA at that time. Chamberlin was born in Kamloops, British Columbia, in 1915. He and his mother came to Toronto after his father was killed in World War I. He attended the University of Toronto Schools at Bloor and Spadina and is remembered by his colleagues and family for being, in his younger days, obsessed with model airplanes which he designed and flew in rapid succession.

He later graduated from the University of Toronto and also obtained a diploma from Imperial College in England. In the early 1940s he went as an aerodynamicist to work for Robert Noorduyn in Montreal. When A.V. Roe Canada (the parent company of Avro Canada) was established in 1945, he joined the engineering team as an aerodynamicist, later becoming head of the small initial project office and one of the senior designers at Avro. His work on the C 102 Jetliner, the first jet transport to fly in North America, the CF 100 fighter, and the supersonic Arrow was largely responsible for the remarkable flying characteristics of those aircraft.

On his appointment as team leader of the Canadians at the Space Task Group at Langley, Virginia, Chamberlin became Gilruthï¿½s close advisor and played a major role in the final design of the Mercury capsule that put John Glenn into orbit on February 20th, 1962 ï¿½ ironically just three years to the day after the abortive cancellation of Canadaï¿½s Arrow project. He became head of engineering and administration on the Mercury project and later head of the U.S. Space Task Groupï¿½s engineering division, directing the multimillion dollar two-man Gemini project and becoming deeply involved in the project Apollo moon lander. Chamberlin received the NASA Gold Medal for his work on Gemini and was described by one of the NASA administrators as ï¿½one of the most brilliant men ever to work with NASA.ï¿½ At the time of his death in 1981 he was Technical Director for McDonnell at the Johnson Space Centre in Houston.

As head of the U.S. Space Task Groupï¿½s engineering division, Jim Chamberlin, born in Kamloops, British Columbia, directed the multimillion dollar two-man Gemini project. Viewed left, the Gemini spacecraft was much more than an enlarged Mercury. Though the two-man crew was still crowded inside a small cabin, much of their equipment was located in a two-part Adapter Module attached to the rear of the Re-Entry Module. Four solid rocket motors were housed in the Retrograde Section, while oxygen, propellants (for the thrusters) and fuel cells (for electricity) were housed in the Equipment Section. The astronauts sat side-by-side, each man having his own hatch and a forward-looking window. [Caption and photo, courtesy NASA via William Mellberg]

While Chamberlinï¿½s monumental impact on the United States space programs has to some extent been recognized in writings about that period, little has been written about the contributions made by the other members of the Canadian contingent who went with him to Langley. All of them contributed to the success of the American space programs, many becoming leaders of the NASA working groups involved in the design, development, launching, and tracking of the Mercury, Gemini, and Apollo vehicles. John Hodge became flight director on the Mercury, Gemini and Apollo spacecraft. Fred Matthews was a back-up flight director to the legendary Chris Kraft and was in charge of flight monitoring and the flight controllers at the tracking stations around the world. Tec Roberts was in charge of the trajectory group in mission control and in 1962 was largely responsible for the design of the Mission Control Center at NASAï¿½s Lyndon B. Johnson Space Centre in Houston, Texas. Owen Maynard, who became chief of the Systems Engineering Division on the Apollo spacecraft, was recognized as the focal point on that program and played a major role in the development of the Lunar Module Eagle, which placed Neil Armstrong and Buzz Aldrin on the moon in July 1969 ï¿½ and the list goes on and on! Perhaps the most succinct categorization of their contributions is contained in Apollo, the Race to the Moon (1969) by authors Charles Murray and Catherine Bly-Cox:

As the Space Task Groupï¿½s burden was threatening to overwhelm it, the Canadian government unintentionally gave the American space program its luckiest break since Wernher von Braun had surrendered to the Americans.... The Canadians ... never gained much public recognition for their contribution to the manned space program, but to the people within the program, their contribution was incalculable.

One of the original American members of the Space Task Group recalled:

They had it all over us in some areas ... just brilliant guys ... they were more mature and were bright as hell and talented and professional to a man.

Some of the exploits of the ï¿½famous twenty-fiveï¿½ have also been captured in other documents, but little has ever been revealed about the contributions to the American space programs made by other ex-Avro Canada engineers. Robert Lindley, chief engineer at Avro at the time of the Arrow cancellation, went to McDonnell Aviation in St. Louis and was in charge of their work on the Gemini spacecraft for NASA. He later joined NASA on the Shuttle program, becoming director of engineering and operations for manned space flight. In 1972 he was appointed director of project management at the Goddard Space Flight Centre. Mario Pesando, chief of project research at Avro, went to RCA headquarters in Massachusetts to work on the Saturn V project to launch the astronauts to the moon. Carl Lindow, formerly project manager on the Arrow project, went to Boeing and became project engineer on their Saturn S-1 and Saturn S-IB rocket proposals. The list of contributions to the American space activity made by the great team of Canadian engineers from Avro could fill a book. It is to be hoped that some time in the future the entire story of this remarkable episode in the development of space technology will become better known.

On a wintry day in February 1962, as four million Americans watched with pride as a cavalcade of limousines slowly made their way along the streets of New York to wild cheers and mountains of ticker tape, Americaï¿½s first astronaut to orbit the earth, John Glenn, waved in appreciation to the crowds from the first car. In the second car was a quiet Canadian from Kamloops ï¿½ James A. Chamberlin ï¿½ Oh Canada!!

After the successful Gemini program in the late 1960s, a grateful American nation presented Jim Chamberlin with a certificate which was not only unprecedented, but which said it all:

National Aeronautics and Space Administration (NASA) Manned Spacecraft Centre presents this certificate of commendation to James A. Chamberlin for his outstanding contribution to this nationï¿½s space flight programs, for the technical direction and leadership of the Project Mercury, for his creation and promotion of the Gemini concept and for his guidance in the design of all manned spacecraft used in the United Statesï¿½ exploration of space to date.
