Extra comments: at between 2:20 and 2:26, the taxing raptor has a small lens on its ventral side, aka Luneburg's lens (that's not cam at all). The lens reflects most of RADAR waves to the opposite direction with magnified and/or manipulated phrases of incoming frequency, allowing RADAR receivers detect the plane very easily. Most likely, common control tower RADARs are not likely to detect F-22, by the way. The lens helps tons to the towers. Recently the digitalized Luneburg lens may manipulate specific bands to send them back, which implies highly secret fake artifacts in RADAR. Their connections are all explosive for eject if needed. Just for tips.
