So, as I said, it appears that it's awfully hard to hide a commercial airliner from military radar. But let's backtrack a bit. Why do aircraft carry transponders? (What is a transponder?) There are a couple of reasons here. First, we need to look at a big problem with radar. It has limited range. We can see this … Read More
