A weird little trivia: for some time period the Skyking test messages used band names and other pop culture references as the content of test messages. Iron Maiden, The Cure, Duran Duran, Rush, Hansen... And of course test messages may be sent erroneously so we end up with the nuclear command channel carrying messages like "DISREGARD 'THE CURE' TRANSMITTED AT 19" (https://eam.watch/view/d4272f25-fd33-47a4-9b37-6c55a8ea3d0e)
