The story is that Sven was having some trouble with his radio. He just couldn't find the transmit button on the stick in his F16. Sven tried pushing this button and that, testing just about all of them except the cannon button, but nothing worked. Meanwhile, up in the tower, Ole decided that Sven must have gone NORDO again, so Ole got out the light gun. As usual, however, Ole couldn't remember which colors to blink, so he just tried every color. All this colorful light flashing got Sven fixated -- Sven just couldn't look anywhere else, and being fixated on the tower, he flew straight toward it. Ole just kept blinking his light, and finally Sven decided he'd better get on the radio and tell his friend, "Ole, you dummy, I see you right in front of me and your light gun button is stuck again." Trying to transmit this message, Sven pushed every everything on his stick, once again, because he still couldn't remember which controlled the radio. Except that this time Sven also tried the button for the cannon.
And now you know the rest of the story.
