G-EBZK  Bristol Type 109 Long Range Biplane                        (c/n  7268)


                                           In the 1920s many experimental aircraft first went aloft with "B" Class registrations.  Each
                                           manufacturer was assigned a letter.  As can be seen, this one-off was previously serialed
                                           R-2 and is still wearing this identity even after being granted a C of A.   This much sparred
                                           aircraft was designed in response to an Air Ministry specification calling for an aircraft with
                                           a non-stop range of 5,000 miles or more.   It carried an unbelievable 900 gallons of fuel in
                                           13 tanks.  In the event a new long distance record of 4,500 miles had just been set in 1928
                                           and it was considered that this was too close to the extreme range of the Type 109 to war-
                                           rant  a new attempt being made.  The project, therefore, was abandoned, and the Type 109
                                           was eventually used as a flying test-bed for the new Bristol Jupiter XF engine.
