"Krypter" is one Colonial equivalent of the "mayday" distress call.
In the Miniseries, Captain Lee Adama loses power to his Viper Mark II after he lures away and destroys a Cylon missile inbound for the civilian transport Colonial Heavy 798. The blast of the missile that he shoots down strikes Lee's Viper and damages his power systems or other avionics needed for navigation.
- According to the closed captioning of the "Hero", which reportedly references the script with a high degree of accuracy, the actual call is presented with exclamation points and not commas, as "Krypter! Krypter! Krypter!"
