 Operational experience had found Blackburn 's Firebrand strike fighter to be far from suited to carrier operations . In particular , the pilot sat near the wing 's trailing edge , looking over a very long and wide nose which gave a particularly poor view for landing . The Firecrest had also been rendered obsolete by the arrival of gas turbine engines , and while Blackburn did draw up proposals for turboprop @-@ powered derivatives of the Firecrest , ( as the B @-@ 62 ( Y.A.6 ) with the Armstrong Siddeley Python engine ) , these went unbuilt , with orders instead going to Westland for the Wyvern . The two flying prototypes remained in use until 1949 , being sold back to Blackburn in 1950 , and were later scrapped .
