Yeah, right.
We're back to "How did they fool the IN (Inertial Nav) system?"
You don't understand that question - do you?
Do you have any idea how inertial navigation works?
It doesn't use any outside electronic data sources. Instead, accelerometers in the aircraft measure its every movement.
In short, in order for the Soviets to be able to lure the aircraft off course by "electronic means," those "electronic means" would have to distort the Earth's gravity field. Ain't no way to do that--or, rather, if the Soviets WERE able to do that, we would've lost the Cold War rather blatantly...
The ICAO investigation found that a rather easy-to-make-error would put the wrong start location into the INS...and that would, in turn, cause the aircraft to fly the wrong direction, Garbage in, garbage out...

The following story is *NOT* an urban legend but happened last year on Sept 5th. Northwest Airlines flight 52 from Detroit to Frankfurt flew to the wrong airport. The pilot was unaware that he was touching down at Brussels despite the fact that the passengers and crew of the plane could all see the GPS system in the cabin showing they were landing in Brussels. The flight attendants decided not to warn the pilots, fearing a hijack was underway and because of rules forbidding contact with the crew on a final approach. The pilot was relieved from duty and a new crew flew to Brussels to collect the flight and fly it on to Frankfurt. It arrived seven hours late.
