The Vickers Vellore was a large biplane designed as a freight and mail carrier, in single-engined and twin-engined versions, which saw limited use as freighters and long-range experimental aircraft.

Leaving Lympne on 18 March 1929 with a full 5,000 lb (2,300 kg) load including the extra fuel, the Vellore II (or Jaguar-Vellore) made Benghazi in stages before engine trouble caused a forced landing.

After spares arrived, the flight continued until the engine malfunctioned again over the Timor Sea, and the Vellore was wrecked in trees near the Cape Don lighthouse at the western extremity of the Cobourg Peninsula on the Australian mainland.

[1] The Vellore III was a twin-engined development that was fitted with a pair of 525 hp (391 kW) Jupiter XIFs with Townend rings and mounted in nacelles cowlings midway between the wings.

[1] The last aircraft of the series was based on a partially completed third twin-engined Vellore airframe, fitted with a new, broader fuselage with an enclosed cockpit, and cabin windows for the passenger compartment, and was powered by 600 hp (450 kW) Bristol Pegasus IM3 radials.

[3] The Vellox crashed shortly after takeoff from Croydon Airport in August 1936 due to a loss of power possibly as a result of a fuel problem.
