OK, help me with this. I understand the radar signature not showing anything, but the military has to track the plane somehow - transponder; something. Unless manually over-ridden or part of the failure, why is that not being picked up? If it did crash, there isn't a signal provided? How, was that turned off too? Are they really wanting us to think that these planes just show up in active military bases and land? No sign of any activity once they are out of sight and just show up" here we are". As has been stated, 2+2 isn't computing.
