Alaska.

This is coolbert:

Once more the Russian air force heavy units flying missions either close to or near American airspace.

"AMERICAN FIGHTERS INTERCEPTED RUSSIAN WARPLANES OVER ALASKA"

Over Alaskan airspace meaning what exactly is not clear.

"SEPTEMBER 20 , 2014 United States officials have attributed the provocation in the sky with the visit of President of Ukraine Petro Poroshenko"

"US fighters intercepted six Russian military aircraft in the area of ​​Alaska."

"'Russian planes stormed the US airspace larger group than usual: Two fighters, two bombers and two tanker'"

To what extent this military adventure is related to the recent deployment of Russian warplanes to the Eastern [Far East] military district only in recent days is not clear.

These aircraft flown in a response to Poroshenko addressing the American Congress? A fit of anger on the part of Putin that gauntlet thrown as a warning?
