We used Trident 2E G-AVFE as a parts source for our aircraft during the restoration project. G-AVFE is currently used by the fire department at Belfast International Airport as a training aid. Find out more about it here.
Martyn Johnson, a former Trident pilot, sent these two pictures of Trident 1C G-ARPN, taken during line training at Stansted Airport in 1964/5.
