In 1998, six Tomahawk cruise missiles fired at Taliban bases in Afghanistan by US destroyers mis-fired and landed in Pakistan. It is speculated that Pakistan and China seized upon the opportunity to reverse-engineer the Tomahawk and develop its own copy, though no evidence exists for this. Pakistan could not have salvaged the embedded systems of the Tomahawks, since they are likely to be in classified programming languages.
I found it in wikipedia while looking for images of missiles.

1)The last sentence does'nt make sense 'cause after you compile any program written in any language you get the machine lnaguage right ? So when you decompile it you should get more or less the same assembly code. Right ???
And even if it is in a known language the reverse engineered code of a complex system will be highly obfuscated(?) right ?

2) And what does embedded sysytems mean ? May be thats what I missed...

Can someone clarify these for me?
Thanks in advance...
