AVRO Arrow # RL 201 during the first, 35 min flight over Toronto - pilot Janusz Zurakowski (March 25/1958) (...) Tremendous power is required to fly an aircraft at supersonic speed and the Arrow used as much power as that taken to drive two ocean liners, the size of the Queen Mary. At supersonic speed, airloads on the control surfaces are extremely high and pilot physical strength must be supported by control mechanisms. Those installed on Arrow were strong enough to lift the equivalent of six elephants. The electronic systems in Arrow required eleven miles of wiring and enough vacuum tubes to equip two hundred television sets
