The Avro 531 Spider was a British fighter aircraft of World War I that did not proceed past the prototype stage. It was a sesquiplane of largely conventional configuration but used Warren truss-type interplane struts, hence being called Spider. In tests, the aircraft demonstrated exceptional performance, handling, and pilot visibility. Unfortunately, by the time it flew, the War Office had already selected the Sopwith Snipe for mass production.
