The Handley PageHerald first flew on the 25th August 1955, from Radlett in Hertfordshire, UK. Designed to replace the Douglas DC-3, it was powered by 4 Alvis Leonides Major piston engines, driving 3-blade propellers. Despite 29 orders from Queensland Airlines, Australian National Airways, and Lloyd Aereo Colombianco, only one was built. This aircraft was registered G-AODE.

A contemporary of the BAe 748 and Fokker F-27 Friendship, the HandleyPageHerald was an unsuccessful attempt at providing a replacement for the ubiquitous Douglas DC-3.
The Herald was designed by HandleyPage's Reading facility, which was formerly the Miles Aircraft Company.
HandleyPage optimised the Herald design for operations from underdeveloped airfields with operators which it thought would prefer piston rather than turbine power.
