Read the process

Provenance — Telliskivi, Tallinn

Made in Tallinn. Tested until it failed, then made again.

Ostrom Aero is a six-person studio above a metal workshop in Telliskivi. Every OA-1 shell is laid, cured and trimmed in the same room it was designed in — one mould, one shell per day, no line to speed up. Certification samples go to the rig until something breaks; the break gets measured, the layup gets revised, and the next shell is better. That loop is the whole company.
