A Northrop F-5E Tiger II of the US Air Force Agressor Squadron based at RAF Alconbury, produced the high standard of display that has now come to be expected of this aeroplane. Powered by a pair of 5,000 lb thrust General Electric J85 turbojets, over 700 F-5Es and F-5Fs (two-seaters) are on order.
The longevity of the Piaggio P-166 has been extended with the arrival of the P-166DL-3, equipped with two 587 h.p. Avco-Lycoming LTP101 turboprops. First flown on July 3, 1976, it will be offered in civil and military variants.
