In order to meet the timetable set by the RCAF, Avro decided that Arrow program would adopt the Cook-Craigie plan . Normally a small number of prototypes of an aircraft were hand built and flown to find problems, and when solutions were found these changes would be worked into the design and then the production line would be set up. In a Cook-Craigie system, the production line was set up first and a small number of aircraft were built as production models.   Any changes would be incorporated into the jigs while testing continued, with full production starting when the test program was complete. As Jim Floyd noted at the time, this was a risky approach, however: "...it was decided to take the technical risks involved to save time on the programme... I will not pretend that this philosophy of production type build from the outset did not cause us a lot of problems in Engineering. However, it did achieve its objective." 
In the late 1800s and early 1900s, through such utopian movements as the Jewish Colonization Association , fifteen Jewish farm colonies were established on the Canadian prairies ;  However, few of the colonies did very well. This was partly because, the Jews of East European origin were not allowed to own farms in the old country, and thus had little experience in farming. One settlement that did do well was Yid'n Bridge, Saskatchewan , started by South African farmers. Eventually the community grew larger as the South African Jews , who had gone to South Africa from Lithuania invited Jewish families directly from Europe to join them, and the settlement eventually became a town, whose name was later changed to the Anglicized name of Edenbridge .,    The Jewish farming settlement did not last to a second generation, however.  Beth Israel Synagogue at Edenbridge is now a designated heritage site . In Alberta, the Little Synagogue on the Prairie is now in the collection of a museum.
