Should you see a Russian military aircraft gliding in the sky in the week ahead, just relax. It’s supposed to be there.

Russia will be conducting an Open Skies observation flight in Finland September between September 2 and 9.

The mission conforms to the Treaty on Open Skies.

Open Skies is a treaty that aims to promote transparency and security in Europe.

The treaty allows the signatories to conduct observation flights and take aerial photographs over the territories of its member states when these have been planned and announced beforehand.

Finland signed the agreement in February 2003.

Russia’s mission strength is 16 persons.
