Does not matter where they come from or how far they flew. Drone ends up in western Ukraine, gets jammed, goes Poland. This is a posibility of among others.
And BTW some of them do go for hundreds of km unchecked or pass by mere saturation of defences, plus and the ones in Poland carried an extra fuel "bag" instead of warheads.
before.. [Occam's razor] the simplest logical version based on available information usually turns out to be the truth
Then it is a provocation. But Occam's does not always work with Ruzzia - sometimes the most abstract "reason" is their "reason".
the 'Gerbera' drones only have normal fuel load to do ~200m(300km) or... ~400m(600km) "with extra fuelbag"
now run the math.. see how far you get.. literally
definitely not russia -> east to west ukraine-> south to north poland to get to the baltic sea
