ZD620 was delivered to 32 Sqn at Northolt in February 1983, where it joined four other earlier 125s for the transport of government officials and military personnel. The final 125s were taken out of service in March 2015. However, due to their age and amount of military modifications, they were not able to continue flying. ZD620 had accrued a total airframe time of 14,000 h as it was ferried to Dunsfold (EGTD) for parting out by Hayward & Green Defence Ltd. The fuselage was moved to the museum for display, where it arrived in October 2015.
