Experimental catapult-launched shipboard fighter using the construction methods developed by the French Wilbault company. Deliberately low-powered with an Armstrong-Siddeley Lynx of 235hp. The Vireo (Latin for greenfinch) suffered handling problems and the Fleet Air Arm lost interest in a low-powered fighters. Neither the Vireo nor the competing Avro Avocet were ordered into production. N211 is test serial, not a military one. Photo from: Imperial War Museums

The plane the centre of a 1920s scandal. Flown by Capt Lancaster from the UK to Australia, the adventurous pilot was accompanied by Mrs Miller, a married woman. The Avian was added to the Australian register as G-AUTU and later VH-UTU. Lancaster and Miller moved to the US where he was charged with the murder of another Mrs Miller's lovers. Acquitted, Lancaster returned to the UK and record flight attempts, dying of thirst in 1933 when he force-landed in the Sahara. Photo from: State Library of Queensland
