On / about December 10, 1941 the MLD flight training school at Morokrembangan evacuated its Ryan STM-2S floatplanes and various Fokker single-engine floatplanes to a small auxiliary base at Lake Grati (approx. 60 KM east of Soerabaja).

Does anyone here know to where the Ryan STM-2 land trainers at Perak Airfield were evacuated? I've seen sources refer to both Malang and Madiun / Maospati. I'm inclined to think Maospat, since Peter Boer shows that at least 16 Ryan land trainers were disassembled there for shipment to Australia.
