The Parnall Panther, designed by Harold Bolas for Parnall & Sons, was a biplane that played a role in the final years of the First World War. 

First flown in 1917, the Panther responded to the call of the Air Ministry for a reconnaissance aircraft that was able to take off from a ship's deck, and was equipped with several novel features, including a monocoque fuselage which could be folded away for storage on board the ship. This wooden, single-bay biplane would have a run of 150, and were one of Parnall & Sons' most successful aircraft, being exported to both the US and Japan. 

In the Panther, the pilot and observer were seated within individual cockpits in the deep fuselage. While this gave a good view for landing, it restricted access to the pilot's cockpit. Its seaplane - specific modifications included inflatable flotation airbags fitted beneath the wings, which could keep the aircraft afloat in the event of having to ditch into the sea. At the front of the undercarriage was also fitted a hydrovane, which prevented the Panther from nosing over.
