Good evening, guys! Thanks for your comment, Hood!
An useful aircraft, so utilitarian that almost there is no place for beauty, its nickname says everything about it: "flying shoebox". But in his uglyness it was a well designed and well built aircraft: The Short Skyvan.
Two aircraft were used by the Austrian Air Force until recently, and a single example was in use by the Ecuatorian Army from 1973 to 1980. The Argentinian Coastguard (Prefectura Naval) used 5 Skyvan since the early 1970s, two of them were destroyed in the Falklands (but the model was stained with the "death flights" during the Dirty War of the Junta). The Skyvan was also a commercial STOL aircraft, and two were bought by Correos de Venezuela in the 1970s until the destruction of both in an accident (both aircraft were empty, fortunatelly) in 1998. And Scottish used the model in short haul flights in Scotland. Cheers.
NB: I am confused with the aircraft in military green that was saw in the Royal Air Tatoo of this year. The Union Jack in not the standart fin flash of the RAF, and this service was not an user of the Skyvan.
