The Chelidon (Χελιδών meaning 'Swallow' in Greek also spelled in English as Helithon) was the first airplane developed by the Greek EAF (KEA) aircraft factory with management provided by Blackburn Aircraft Limited at the time. According to one source it was designed by Charles H Lowe-Wylde although in the contemporary Jane's edition it is mentioned that it was designed largely by Greeks (under the supervision of Mr. Wylde) according to Greek Navy specifications.
Made by State Aircraft Factory (Greece)EAF.
