A/S Aero A/S Aero A/S Aero was a Norwegian airline company founded by Tancred Ibsen in January 1920. The company was financed by Tancred Ibsen's uncle, businessman Einar Bjørnson, and two shipowners. Despite the "A/S" (for private company limited by shares) in its name, A/S Aero was never formally registered as a limited company. The company purchased one Hansa Brandenburg W.29 and four Friedrichshafen FF.49 aircraft from Germany in February. This deal was probably illegal as the Entente prohibited the export of German surplus aircraft, but Ibsen nevertheless got permission from the Norwegian Ministry of Defence to import the five German aircraft.
Mosphil Aero airline started operations in November 2006, backed by Russian interests, with over 40 employees (at March 2007). Mosphil Aero hoped to launch its Zamboanga City-Sandakan-Kota Kinabalu route on 30 August 2006, subject to obtaining the relevant permits. Aircraft would initially be operated by Russian crews while the Filipino pilots undergo training at the Antonov Training Center in Kiev, Ukraine. Following a test flight in late August 2006, Mosphil Aero operated its first commercial flight from Zamboanga to Sandakan and back on 12 November 2006 using an Antonov An-24 aircraft with a Russian crew. The service will operate three times weekly.
