Sure, but over Belarus their guidance and comms are not jammed. So either they were autonomous and not jammed when they flew into Polish airspace or they were guided and flew there on purpose. The 'unguided but jammed' combination does not work for the flightpath that they took.

BTW, they can be taken over post launch as a rule, this is one of the things that makes them a bit harder to take down, they don't follow a predictable trajectory and can react whilst underway. There are also jet powered versions that are a lot faster that are harder still to take down. The ones over Poland this morning all seem to be the prop based ones. There is also talk of at least one missile.
