My main takeaway from the article is that it is scary that aircraft safety is so dependent on a signal that is so easily generated and spoofed. From the article it sounds like anyone can go to an airport and simply send some garbage signals towards an approaching aircraft to make it deploy air breaks and crash if the pilot is not quick to react. When I think about it it seams like a common thing in aviation tech. ads-b has similar issues, it is completely unauthenticicated/unsigned there is 100% trust. Anyone can pretend to be anyone else.
