 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 ( <unk> ) with the Armstrong <unk> <unk> engine ) , these went <unk> , with orders instead going to Westland for the <unk> . The two flying prototypes remained in use until 1949 , being sold back to Blackburn in 1950 , and were later scrapped .
