From Military Archives of Finland. The accident happened on 20th March 1943 when PY-12 (1941, 106 h) taxiied straight into PY-10 (1939, 367 h) which was at the stand. No one was hurt, but PY-10 was badly damaged and had to be transported to Tampere for repairs. These are unpublished photos.
The aeroplane is Finnish-made VL Pyry advance trainer.
From a different accident. The pilot accidently let air flow into the engine and hence the engine was shut down.
The last one (and the last flight of this particular pilot, R.I.P).
