Amazon Prime Air says it has received what it calls the world's first SAIL IV operating authorisation and SAIL IV flight worthiness validation, issued by the UK Civil Aviation Authority, Dronewatch Europe reports. David Carbon, vice president and general manager of Amazon Prime Air, announced it on LinkedIn on 7 November and said it took several years of engineering work with the regulator.
SAIL, the Specific Assurance and Integrity Level, comes from the SORA method for assessing the risk of complex drone flights, including beyond visual line of sight. Of its six levels, SAIL IV is one of the more demanding but not the highest. Amazon has not said where the approval applies or what limits come with it.
Dronewatch Europe notes several incidents with Amazon's MK30 drones: two crashed in tests in Pendleton, Oregon, in December 2024, two hit the same crane in Tolleson, Arizona, on 1 October 2025, and one was substantially damaged in a test flight in Darlington, UK, on 29 July 2026.
