Undetected, unexpected
Wings of glory
Tell their story
Aviation, deviation
Undetected
Stealth perfected
From the depths of hell in silence
Cast their spells, explosive violence
Russian night time flight perfected
Flawless vision, undetected!

when you're hungover as shit after a spending a night drunk as a skunk
