AALTO secures UK CAA Design Organisation Approval
The UK Civil Aviation Authority granted AALTO Design Organisation Approval, a prerequisite milestone in the Zephyr Z8 type-certification process.

Evidence notes
- The approval was the first UK Design Organisation Approval issued to a HAPS company.
- The CAA reviewed AALTO's procedures, facilities and design-team competence.
- AALTO continued type-certification work for Zephyr; the approval was not itself aircraft type certification.
Company context
AALTO designs, manufactures and operates the solar-powered Zephyr high-altitude platform for stratospheric Earth observation, government missions and communications services.
