Until the demise of the HS748 from Her Majesty's Australian Air Corps order of battle there was the Howlettes. For those not in the know, the name is a dig at the Roulettes, the official RAAF display team. The Howlettes diplay comprised of three (sometimes, my God, four) 748's in close(ish) form at zot feet (er, 500 AGL) and close to Vne (a mighty 260KIAS). Let me tell you, three (or four) 40,000lb dog whistles in close form was quite a sight. They were billed as the world's only "straight and level aerobatic team"
