Or it could be much like the Soviets when they shot down a Korean passenger jet carrying innocent passengers as hostage on an American spy mission.... as the Soviets claimed. I find it difficult to believe a pilot could fly that far off course accidentally. Its possible that the airplane was carrying surveillance equipment. The Soviets claimed the airplane flew directly over a top secret facility in the middle of test. Also the Americans were playing cat and mouse games at the time. The Soviets just chased off an American spy plane, when the Korean airliner flew into Soviet airspace. Also the American military made a huge effort in order to be the first to recover wreckage.
I suspect in that case and in this one, the truth will remain a mystery...
So, you have problems believing a pilot could fly off course accidently and therefore lean towards believing the soviet explanation of "innocent passengers as hostage on an American spy mission".
That says a whole lot about you right there.
Personally, I'd want to get to the wreck before the soviets too, then I'd be assured that the soviets didn't plant any "evidence" to support their side of things.
and yes, I'd believe the americans over the soviets when it comes to this. Where as you, would believe anyone or anything besides the americans or the Israelis.
