Its not something you see everyday, a Russian Spy plane flying over parts of Rhode Island and Eastern Massachusetts.

It happened Friday, according to Boston Herald photographer Mark Garfinkel.

Garfinkel is somewhat of an expert on international aircraft and tracked the aircraft's movements using the internet.

He later snapped a photo (above) of the unarmed jet over South Boston, probably in the vicinity of the JFK Library.

It turns out the Russians were not breaking any rules.  The flights are allowed under the 2002 Treaty on Open Skies, which allows the U-S and Russia and 32 other nations to make observation flights to help verify compliance with arms control agreements.
