 So, big things, last thing for the future here and including this year is the electromagnetic spectrum. We have to get much better at it. Our adversaries, our potential adversaries are improving dramatically in it. We are out there spewing electromagnetic energy into the air and we don't have that control of our mission called MCON, a mission control that we had in the Cold War when the Soviets were quite good at detecting electromagnetic radiation, i.e. radars and that. And we've really never had a pier or anybody close to that and we've gotten really sloppy. But electromagnetic spectrum is also an entryway for cyber. You get into that and you can get to places and get into networks, you can do some stuff.
