First flown on August 17, 1961, the HP.115 was designed to study the low speed qualities of the ‘slim delta’ wing proposed for the Concorde, at low speeds.
It had a Viper 11 for some of the early testing that was borrowed from Huntings Jet Provost 3. The nosegear was from a Jet Provost 3 and the main gear from a Piston Provost. In the cockpit the parking brake lever came from the local Ford dealers for an Anglia car.

At nose, tail and wingtips there were some detachable steel weights for test, which came from the jig scrapyard and were made into aircraft material under duress from the AID.
