Having entered service as one of the first-generation executive jets, the British Aerospace 125 has been operated by a wide variety of customers, ranging from government and military operators to private customers and businesses, it has also seen use by several airlines. Many of the aircraft's customers have been located in North America; in 1990, out of the 650 aircraft then being operated, more than 400 were being flown in the United States.  Reportedly, one aircraft was being sold every seven working days for a substantial period of the type's production life.  Successively larger versions were introduced to extend the type's appeal and to better compete against larger jets being used for business travel, such as the Gulfstream IV and Falcon 900 . 
The engines and fuel tanks were recovered from Seafarer and used in another Dragon named Seafarer II . After three attempts to take off from Wasaga Beach, Ontario , Canada for Baghdad , Iraq, the attempt was abandoned and the aircraft was sold. On 8 August 1934, the new owners, James Ayling and Leonard Reid, took off in the Dragon, renamed Trail of the Caribou , from Wasaga Beach in another attempt at the distance record. Although the intended target was Baghdad, throttle problems forced the attempt to be abandoned, and Trail of the Caribou landed at Heston Aerodrome , an airfield west of London, in Middlesex, UK after 30 hours 55 minutes, making the first non-stop flight between the Canadian mainland and Britain.
