Photograph of the first Challenger on the occasion of its roll-out in Montreal at the end of May 1978. Flight testing of this and the next two aircraft will be based in California to avoid weather delays during the coming Canadian winter.
Canadair has tooled up for production of up to seven Challengers a month, and the first aircraft was built in production jigs. The illustrations show the Challenger's one-piece wing, and front fuselage sections in production.
The Challenger, with its distinctive T-tail, has a somewhat stubby external appearance, resulting from the decision to adopt a "widebody" layout.
