A pilot who was presumably bored decided to trace a giant penis on the flight tracker while flying an aircraft over a lake in California that, on closer look, already has a phallic shape.
The "aviation boner" was reportedly created by the pilot of a Navy T-34C Turbo Mentor trainer, a plane that is normally used for bombing range spotting and clearing duties.
The plane flew the penis-shaped trajectory over Southern California's Salton Sea.
The flight path was spotted by Twitter user @AircraftSpots and shared on the social network.
