“Because Polish government’s plane TU-154 carried among other Polish highest ranking officials head of NATO state and its highest Army’s commanders. According to reports, many were carrying electronic devices with sensitive NATO data. Russians acquired ultra secret codes used by NATO militaries for secure satellite communication.
if the Russian electronic intelligence service, known as the Federal Agency of Government Communications and Information, was able to recover and use the communication key code from the wreckage, electronic spies will be able to decode months’ or perhaps years’ worth of scrambled communications that are routinely gathered electronically for just such an occasion.
The coded communications, if decrypted, would reveal some of NATO’s most intimate secrets, such as plans for defenses and even the identities of agents or allied eavesdropping sources.”
This sounds more like a Beartrap.
To make things worse, about a year before this crash a Polish army codebreaker disappeared. http://afpc.org/publication_listings/viewBulletin/971
There were rumours that he defected to China. Several days after the crash most probably his body was found in the Vistula river in Warsaw (the body was so decomposed that it was difficult to establish his identity). But it also does not appear to be coincidence.
