Boeing Starliner flight 2022 – FLOWN ISS cover

An exceptional flown cover celebrating a milestone in human spaceflight — the Boeing CST-100 Starliner’s Orbital Flight Test-2 (OFT-2) mission.

Postmarked May 21, 2022, the date of Starliner’s historic first docking with the International Space Station, this cover represents the long-anticipated success of Boeing’s crew vehicle in reaching and berthing with the ISS.

Enhancing its rarity and appeal, the cover is personally signed by Russian cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov, members of the Soyuz MS-21 crew aboard the station at the time.

A remarkable philatelic tribute to a pivotal step in commercial spaceflight and international cooperation in orbit."
