"The Bernard 80 GR was one of three types built by different French constructors in response to a government call for an aircraft capable of setting new long distance records. A single engine monoplane with a crew of two,
the 80 GR set an absolute record for flight over a closed circuit in April 1931, covering 8,960 km (5,569 mi). Modifications led to a new designation as the Bernard 81 GR but no more records were set despite several attempts."
