Actually, the plane wasn't a spy plane and the Red Chinese didn't force it down.
And while technically correct, it wasn't forced down (that we are told about, but then again, you may be in the secret circle) it did collide with a chinese fighter, which had scrambled to intercept it and was forced to land on chinese soil.
Wrong on both counts. They were listening to preparations for a nuke test and they were forced down by a fighter that bumped their aircraft. The Navy pilot was heroic in avoiding a crash landing.
