Finnish PM is useless as anything but an anchor weight and would probably suck in that too. He should travel in a railroad car at best or perhaps by bus. Tax money wasted in sending him around. Much better guys to travel. Other than the rant above. The story is very simple: Russians dropped by, didn't inform anyone on the flight, they where seen and went away.
The KAL flight. Anyone that has spent his or her early days (30 something) in the north will see from the KAL pic that the trees are typical of a marsh area of a lake and an abyss of note easily capable of sinking an airliner. Looking at the pic the aircraft rest just at about where the weeds and marsh begins and open water ends. ( I am 100% Karelian btw and it used to be a beautiful area before it was stolen by Soviet Union in an illegal and internationally condemned attack)
Piombo. You have gotten the KAL story totally wrong. They where no invited to land. They where shot down. PAX was killed by as Missile that went through the fuselage. The damage is clearly visible on the fuselage just around the trailing edge of the left wing and the wing itself. PAX killed where 2 not one. Aircraft suffered a rapid decompression and the forced to land on the lake. Some invitation eh?
