Canadian aviation prowess, a prime factor in welding tight the widespread, boundless reaches of a vast country, has often flown leader in new aerial techniques. Air photography for map-making, low-pressure balloon tires for landing on virgin territory, airborne geophysical observations, landing devices for securing helicopters during rough weather at sea -- these developments stem from a people made air-minded by circumstance for fifty years. Today, with exports taking a strong, climbing turn (1964 saw a 130 percent export gain to a total value of about $250,000,000), the Canadian aviation industry, linked with its lusty young partner, the aerospace business, is looking forward to the future. From a twin-engined aircraft that can take off and land vertically and yet travel at 350 miles per hour, to vital satellite parts and scientific rockets, from ultra-sophisticated navigational systems and aircraft simulators to airplane galleys including the kitchen sinks, Canada's manufacturers are now placing fifth in what is probably the most competitive business in the world. With a line of famed, special-purpose aircraft to their past credit -- the hard-working Beaver and Otter, the swing-tail CL 44 and Caribou -- new shapes are now appearing in the yawning hanger doors. In Montreal, Canada's new CL 84 tilt-wing, VTOL aircraft is under power tests. In Toronto the sturdy FBA-2 utility freighter has already been built for buyers ranging from logging companies to charter services. In Winnipeg new, super-Black Brant Mark IV rockets are readied for the upper atmosphere and in Georgetown, Ontario a successful cross between a helicopter and autogyro is proving its versatility. Canada's aviation industry is zeroed in for wider, brighter skies.
