RWD-9 recon plane in flight.
RWD-9 was a sport plane built in a small series for the Challenge in 1934 (which btw. was won by Poland). No military use at all.
RWD-8 (the one with the female pilot standing in front of it), was a training aircraft (incl. training of flying using instruments only).
The sea plane was the Lublin R-XIII ter, woefully outdated in '39. That was a recon plane. Other recon plane was the RWD-14 Czapla.
