During the cold war did the Russia do fly overs over the united states?

Did the Soviets do fly overs? They sure did, in fact one could fly from St Petersburg or Moscow to JFK and many other places.

Nope, no Soviet flyovers.

The Soviets had no bases close enough to the US because of the US being on it's own continent with just friendly Canada/ Mexico/ Central America and US/ US allies being in control of the oceans on both sides....and they couldn't use Cuba because it was blocked.

The Soviet Union on the other hand sat on a continent with dozens of non Soviet countries all around it, so the US could have air bases all around it to do recon flights from.

The best the Soviets could do was try and fly over the polar ice cap to fly through Canada to get at the US but that was blocked by US polar submarines and the joint US-Canada radar net called...NORAD and DEW line, so the Soviets could never get through.

P.S. Gary Powers flew from a US air base in Pakistan for example right near the Soviet border.

They sure did, Fred. In experimental saucer-shaped craft that the American public imaginatively named "flying saucers" (because they were saucer-shaped, y'see. And they flew.)

No they didn't. They were more responsible.
