The developmental series eventually culminated in ReserVec. ReserVec was the first computerized reservation system to enter service when it took over all bookings for Air Canada in 1961. Ferranti initially had high hopes for the machine, thinking that it would be successful in Europe if sold by the UK headquarters' sales staff. As had happened many times in the past, however, the UK computer team suffered from a terminal case of not invented here, and decided it was better if they designed their own instead. Their project was never delivered, and ReserVec withered.
