Description
After taking off on 11th July 2018 in Arizona, the Zephyr S unmanned aircraft from Airbus Defence and Space logged a maiden stratospheric flight of over 25 days – the longest-duration flight ever made without refuelling. Following this flight, the UK Ministry of Defence ordered three of these systems.
Sheets of specially designed Royal Mail personal smiler® stamps were flown aboard Zephyr S to mark this historic flight and are to be used to service commemorative covers ordered by the Defence company.
