Britain's Four-Jet Delta Bomber May Fly Over Air Show -- An impressive view of Britain's first delta-wing jet bomber - probably the only one of its kind in the world - the Avro 698. The plane made a 36 minutes maiden flight recently, and is expected to put in a flying appearance at the society of British Aircraft Constructor's show at Farnborough, Hampshire. It has been disclosed that the British Government decided to order an appreciable number for Royal Air Force without waiting flight trails.
