I got this photo in an auction lot, but couldn’t identify the airplane. At first, I thought it was a British biplane, perhaps something from Hawker. The lack of any lower wing threw me a bit, though… While researching the previous post, I found a mention about the Belgian Air Force, illustrated with a biplane. I checked the Wikipedia article on the BAF in WW2, and the types of planes that were flown. I checked one, and – bingo! The plane in the photo is a Renard R.31! Further searches yielded a photo that was most likely of the same wreck. This is what makes this kind of research fun.
As for the Renard R.31, it was a Belgian reconnaissance aircraft which first flew in 1932. It was the only military WW2 aircraft entirely designed and built in Belgium. The R.31 entered service with the Belgian Air Force in 1935, but it wasn’t popular with its pilots, as it had poor handling and was vulnerable to entering flat spins. Only 34 R.31s were built. It was obsolete when Belgium was invaded in 1940, and those that were not destroyed on the ground in the early hours of the German invasion were savaged by German fighter planes as they attempted to gather information on the invading forces.
Following the German occupation of Belgium, the Luftwaffe showed no interest in the R.31s, and those that had survived were unused or destroyed. Overall, these machines had no significant impact on the Battle of Belgium.
